Ottimo prodotto, ben costruito, ideale per provare circuiti in laboratorio. Consigliato!!
Allerdings gibt es ein wesentliches Manko: Auch nach dem Umschalten auf Echtbetrieb wird nur die e i n g e s t e l l t e Spannung angezeigt, nicht die anliegende. Spannungsabfall bei wechselnder Belastung ist so nicht kontrollierba
Das Labornetzteil kam super schnell und sehr gut verpackt gegen Transportschden. Die technsichen Daten werden sehr genau eingehalten. Die hellen Digitalanzeigen sind extrem genau (Vergleich mit einem Fluke Digitalmultimeter). Der Einstellvorgang mit Strom und Spannung geht sehr schnell. Was strt ist das Piepsen bei jedem Einstellvorgang. Im Setup kann man das zwar abschalten, ist aber nach dem nchsten Start wieder aktiv. Insgesamt eine klare Empfehlung.
Fa il suo dovere….lo usato per bilanciare batteria al litio e fa il suo dovere.
I’m not experienced enough to write a full review. But I’ve chosen this brand and model, because there were individual buttons for power and output, the voltage and current knobs were encoder knobs and basically the device was looking very nice. I’ve measured the output and as others stated it is quite accurate. I’m very happy that I bought this device, and I definitely would recommend it.
Das Gert kommt im Hobby-Bereich zum Einsatz und ist ideal und bestens fr meine Anwendungen geeignet.
As a amateur tinkerer and maker this bench top dc supply has been worth its weight in gold and I would highly recommend it as a beginner device. It has a supported range of 0v to 30v volts and as someone that works with LEDs and consumer electronics like consoles this comfortable covers everything I need (my needs generally max out at 24v). I don’t own an oscilloscope yet to check the quality of the output empirically but the delivery gives stable results in my projects so far and I’ve experienced zero issues with line noise and load-relative fluctuations. The satin black finish and high contrast displays look some much more modern than the beige ones also!
Eccezionale, fa quello che promette, ho provato a misurare con tester(non professionale) e la corrente erogata e corretta
I have been meaning to get a PSU for ages and had this in my wishlist for a while, picked up the 30V / 10A version for 60 on Prime Day excellent. I doubt that I will need 300W of power, but always nice to have under the hood for the same price as the 150W PSU. The unit is surprisingly small but well specified and not short on features.
The buttons have a reassuring notched click to them when turned, and they also beep, however I quickly turned off the beeping using the system settings menu. The white LED on black display is large and clear and a definite upgrade to the retro red LED displays. As displayed the unit is very accurate and should be fine for most applications bearing in mind that test leads have some resistance, and also test meters may also have a slight tolerance, unless you are a lab tech using calibrated equipment, this should be a welcome addition to your test bench. Inside the unit is neat and tidy, and uses suitable gauged cable and connectors to handle loads upto 10A. I didn’t see the fan in operation, as it is trigger by temp I probably need a sufficient load.
This leads me to my minor grip with the unit, the binding posts are cheap as chips, they are okay I suppose, but not the type that I have been used to. There are no holes in the posts to thread cables through if you are out of banana plugs, or want to link the terminals together, and the black knobs can actually be unscrewed completely from the posts which could lead to them being lost? As someone has also posted that one of their binding post snapped off I decided to swap them out for some others that I found on Amazon and they look great.
Also if you are after a pdf version of the manual head over to wanptek.com where you can download a copy.
Overall very please with the product, appears solidly built, great functionality, and I got it at a great price, just go easy on the binding posts.
Ich bentigte ein Ersatz-Ladegert fr meine 24V Blei-Gel Akkus.
Direkt getestet, wie sich die Spannung am Gert verhlt wenn die Akkus voll sind und wie genau die Spannungsangabe auf dem Display ist und wie sich der Strom begrenzen lsst.
Alles vollkommen im normalem Bereich. Das Gert passt stndig den Strom beim Laden nach unten an, so dass die eingestellte Spannung an den Akkus nicht berschritten wird und diese somit nicht berladen werden knnen.
Bedienung wie bei alten, guten Labor Netzgerten. Top, sehr einfach zu bedienen.
Wie ich in der Bedienungsanleitung gelesen habe, lassen sich die Parameter speichern und stehen beim nchsten Einschalten sofort wieder zur Verfgung.
Was soll ich sagen, das Gert ist viel besser und leistungsfhiger, als von mir erwartet.
Top Gert, wrde ich sofort wieder kaufen.
A very versatile and truly useful addition to anyone’s workshop. It is accurate, easy to use, and is a neat and tidy unit. I love it !!!
Does what it says ,run this at full power on my de rusting tank and works perfect, fan comes in and out but never felt hot in use, just warm, the leads did get quite warm though – so will look at upgrading those.
Surprised how good these are for the money.
Great product and easy to read clear display, nice and light as well. All good!
Anders als in einer anderen Rezension beschrieben ist das Netzteil meiner Meinung nach geeignet einen Raspi ber USB zu betreiben (zumindest hat es bei mir funktioniert und der USB Ausgang liefert mindestens 2A/5V an einem passiven Widerstand).
Aber Achtung: USB GND ist mit Minus verbunden.
Fr ein NoName Netzteil sehr gut verarbeitet.
Die angezeigten Messwerte stimmen ebenfalls sehr genau.
Test bei Dauerlauf und Voll-Last ebenfalls bestanden.
Bought to replace my old & malfunctioning Maplins power supply. Useful for a large variety of projects. As of now, only used once to power a 12v music amp, Everything worked fine, adjusting the amp is easy, and the displays are clear. Very pleased with my purchase.
sondern fr meinen PC-Arbeitsplatz, an dem ich hauptschlich
fr Microcontroller codiere (RasPi, Arduino, etc.).
Deshalb sind hier 30v/5A mehr als ausreichend.
Fangen wir doch einfach mal mit den wenigen Negativ-Punkten an:
1. Jegliche Bedienung wird mit einem nervigen Piepsen kommentiert.
Chinesen scheinen das zu mgen, ich nicht.
2. Statt des USB-Schnellade-Ports htte ich mir einen Standard-USB-Port
mit 5V/3A gewnscht, um daran z.B. Raspberries zu betreiben.
3. Das Teil kam nicht originalverpackt.
Die Schutzfolie auf dem Display war offenbar schon einmal entfernt
und wieder aufgebracht worden.
Auf der Gehuseoberseite gibt es leichte Kratzer.
Nicht bis auf das blanke Blech, deshalb ertrglich.
Warum ich trotzdem fnf Sterne vergeben habe?
Ich mag es einfach, wenn sich Entwickler Gedanken ber die Bedienbarkeit machen.
Und dies dann auch gekonnt umsetzen.
Klar, es ist nur ein Netzgert.
Man stellt Spannung und Maximalstrom ein, meist mit Grob- und Fein-Potis.
Und dann kommt unten raus, was man oben gewhlt hat.
Das es auch anders geht, zeigt dieses Gert.
Die Einstellelemente sind Rotations-Encoder mit Taster-Funktion.
Ein Druck auf den Knopf whlt die Dezimalstelle, ein Drehen zhlt auf oder ab.
Beispiel: Sie sind bei 5V und wollen schnell zu 25V wechseln?
Drcken Sie “Voltage” bis das 10V-Digit blinkt
und drehen Sie zwei Raster nach rechts. Fertig.
Die gewhlte Dezimalstelle bleibt auch nach dem Ausschalten gespeichert.
Genauso geht es natrlich auch bei der Strombegrenzung.
In dieses wohlberlegte Design passt auch der “Output”-Knopf.
Er macht nichts Anderes als den Ausgang freizugeben.
Schn zu haben, denkt man sich; ich kann doch auch den Stecker ziehen.
Sicher, kann man, aber dieser Knopf ist komfortabler.
Ausserdem wird im AUS-Modus der gewhlte Maximalstron angezeigt,
im EIN-Modus der gemessene.
Aber nicht nur das Konzept, auch die Umsetzung berzeugt.
Jeder Rastpunkt der Encoder zhlt genau ein Digit weiter.
Das dies nicht sebstverstndlich ist, weiss jeder,
der so ein Teil mal in seinen eigenen Projekten benutzt hat.
Analoge Einheiten digital zu steuern und zu bedienen
stellt eine grosse Herausforderung dar, auch wenn es “nur” um ein Netzgert geht.
Die bei diesem Teil gefundene Lsung ist in meinen Augen genial.
Und genau deshalb vergebe ich fnf Sterne.
Und, nein, ich werde nicht vom Lieferanten/Hersteller gesponsored.
Ich habe das Netzgert 30V/5A normal erworben als der Preis kurzfristig bei 58 lag.
Buon Alimentatore con in ottimo rapporto qualit prezzo, la tensione visualizzata sul display effettivamente quella erogata (controllata su vari carichi con 2 test di buona quali
Mi serviva un alimentatore duale con cui poter simulare due lipo 3S collegate in serie, un discreto alimetatore duale costicchia parecchio e a conti fatti ho preferito prenderne due uguali ed usarli in serie, devo dire che la comodit di regolare la tensione con un encoder ottico spettacolare, pu essere variata decidendo se agire sui volt, i decimi di volt o per variazioni davvero piccole anche sui centesimi di volt rispetto ad altri alimentatori che ho con il classico potenziometro qua la regolazione fluida senza inceppamenti o salti dovuti all’usura del potenziometro, inoltre come alimentatore presumo sia anche ben tarato visto che entrambi settata la stessa tensione danno anche gli stessi valori di assorbimento. Il tutto lavora sui 24v che a loro volta vengono ridotte con i tipici stepdw e alimentano un arduino mega e parecchi motori in dc di diversi voltaggi, senza nessun problema o reset di arduino. Non posso esprimermi in merito alla pulizia della tensione o ripple residuo ma almeno per le mie prove da hobbista sono molto soddisfatto.
Nice small power supply, just what I needed to power my small amateur radio when using it in the garden.
A m me ha parecido una buena fuente de alimentacin. No le estoy dando un uso super-intensivo ni me dedico a hacerle pruebas de carga ni nada por el estilo (como he visto en algunos canales de YouTube donde la han probado). Por ahora, y simplemente, la uso para probar tiras LED de 5/12V y alimentar algunos mdulos para Arduino cuando estos requieren mayor corriente que la que puede proporcionar la placa de Arduino que tengo (una Arduino UNO) y va muy bien. Justo lo que necesitaba. Ni ms, ni menos 🙂
Como se ve en las fotografias hay unas decimas de diferencia del voltaje a consumos por encima de los 7 amperios. llegando justo a los 10 amperios, la fuente corta el suministro. Todo medido con carga electronica, que por cierto me indicaba una tension distinta a la del multimetro y a la de la fuente de alimentacin. Hay caidas de tensin en los cables de la resistencia electrnica y las tolerancias de esta. La fuente en si muy bien, templada a altos consumos, ventilador automatico bastante silenciosos. Muy intersante la programacin de voltaje y amperaje “antes” de la salida, es muy practico para consumos muy especificos. el control de las salidas digito a digito es perfecto.
Compact power supply with nice bright display and very easy to use
Das Labornethteil ist sehr gut verarbeitet und funktioniert einwandfrei! Ich bin mit dem Netzteil zufrieden und wrde es wieder kaufen.
Eine gnstiger gert und doch von guter Qualitt.
Sehr einfach zu bediene
This product is very useful for many different tasks, especially if you want to charge up devices that you don’t have a charger for anymore. It’s also very easy to use.
The default setting after unboxing it should probably better be something harmless, alike 5V / 1A.
La costruzione buona. L’assemblaggio fatto apparentemente bene, I display sono ben leggibili e anche l’utilizzo molto intuitivo. Se devo cercare un difetto sono le boccole in uscita che potevano essere migliori; per per il prezzo che ha a qualcosa bisogna per forza rinunciare.
Il rapporto qualit prezzo secondo me ottimo.
Va detto che l’elettronica di tipo switching e non a trasformatore ; magari qualcuno preferisce un elettronica di tipo lineare per cui si deve orientare su un prodotto diverso.
MUY BIEN HECHO DE LA CALIDAD
en pocos dias disponible, el precio no mucho mas que pedirlo en China y esperar unos meses!
Great sturdy unit at a good price. My recently calibrated Fluke tester shows it is accurate to 0.1v which is all you can ask for.
Fuente regulable de 0-30 volt , prctica , para experimentos de laboratorio
Better than expected , really well designed, very simple to use
I’m very pleased with this power supply. Seems very well made, with an easy to read display and intuitive controls.
Voltage and current limiting seems accurate.
I had to use it as a temporary power supply for a 500mA electromagnet on a door for a week, and it ran continuously with no obvious heating.
Bastante precisa, muy bien de tamao, pesa muy poco y muy fcil de usa
Addressing the criticisms I’ve seen first, in descending order of importance from my own perspective:
(1) Noise: [updated]
One reviewer said that the output had noise on it; I checked (off-load) with a ‘scope and yes, it does. Fast switching transients, most of it is under 200mV peak-peak in amplitude, with a max of perhaps 400mV peak-peak, at different frequencies. This is quite a bit for low voltage o/p. Switching noise hardly a big surprise on a switching power supply, but because it’s very fast transients, it is quite hard to get rid of. As you turn up the output voltage, the spikes don’t increase in amplitude but do become more frequent. The manual quotes max ripple (current) of 0.5% and “voltage stability” of 0.5%. The fundamental output voltage seems absolutely rock steady, to be fair, but the noise is relatively fast impulse type noise; while the pattern of successive spikes is some syncopating mix of switching frequencies, in the region of tens of kilohertz, each spike is sharp-edged which means overall it’s an episodic pattern of, in effect, very high frequency components. On my ‘scope I see a rapidly diminishing “ringing” at about 450KHz, halving in energy every cycle and negligible after about 5 cycles, for each spike, so the 200mV spike lasts about half a microsecond according to my (slowish) ‘scope but is probably in reality much shorter, and the ringing is probably on the connection wires. I initially thought that typical decoupling and other load capacitance would soak this up, but the sharp pulse edges instead get everywhere. Linking the -Ve output terminal to the centre ground terminal seems to help. I opened it up to take a look – there are no ferrites in the output wires, nor did I see any chokes near where the output wires leave the main board. I’ve docked a star because while I like the way it looks and works, I’m going to have to make some modifications to try to reduce the switching noise.
(2) Mains cable being loose.
I thought the reviewer who said this must have had a dodgy cable. Then I plugged the one supplied in and thought maybe they had a point, but then I realized it wasn’t fully home. When plugged in, it feels like it’s gone all the way in and is loose. It has another 5mm or so to go – push it firmly past this stiffness and it snugs into place and is nice and firm, at least on my one.
(3) Control convenience:
A YouTuber bought one of these and complained that when the output is switched on, adjusting the voltage also sets the current display into “entry” mode so it shows the preset current rather than the metered current. It goes back to “live” readings after a couple of seconds hands-off. (To make this clear – you adjust voltage and current with the output switched off and the voltage is what it will output, and the current is the current limit you set. Once the output is turned on, the current and voltage displays go “live”, so if the load is drawing less than the preset current, that is displayed, if the load is trying to draw more than the preset current, the current will be close to the preset and the voltage will have dropped to keep current below the preset. If you’re within the limit, though, the YouTuber reasoned that the thing should continue to show live voltage and current when adjusted with the output on. That way you can manually adjust voltage to achieve a desired current. For me, this is not a use case I care about – if I want to monitor the current in real time while adjusting the voltage I can just use another current meter, but mostly I’m only interested in setting a current limit that will prevent short-circuit damage.
Another control feature is that while the device remembers the presets when you turn the unit off and on or unplug it, by default it always starts in output-off mode. This, to some, is an inconvenience because it means you can’t leave it unattended as the sole power of something that you want to be on all the time, because a slight blip in the mains supply will cause it to reset and turn its output off. To me, though, for a bench PSU this is the way I want it to work, especially if there are people around who might have fiddled with the voltage etc while you weren’t looking. At work, we have a bench PSU that comes on with the output in whatever state it was when switched off, and a couple of boards have been blown up by people turning it on connected, after someone else has left it set to a high voltage and output on. For me, then, this one works the way I’d want it to. HOWEVER, this feature can be altered via “system settings” – see below.
The only other “user interface” thing I think might be of concern to some is the bleep on startup. I actually, unusually for me, looked at the manual to see if this could be switched off, and found somewhat to my surprise that yes it can, there are a number of “system settings” you can get to by a long press (5 seconds) on the output switch. System settings are as follows:
1. Machine ID (see comms)
2. Output state on power-up (so it can come on in “on” or “off” state)
3. Screen brightness
4. Buzzer mute (yay!)
5. Comms baud rate
6. Comms little- or big-endian.
The comms features are for an option serial module that allows remote control – again, bit of a surprise, this.
Personally, I’m totally happy with the defaults, except perhaps the bleep (though it’s not that obtrusive).
Features, observations, summary:
As others have said, the output voltage seems accurate, certainly by the standards of regular hobby- or professional-grade meters and the like. Someone with lab-standard high-resolution calibrated meters might find something to complain about, but I would consider it “good enough” for any normal purpose. The number of decimal places for the current display might be a bit specious, I daresay it’s not actually accurate to a milliamp, but it’s not something I care enough about to check.
The way it operates seems exactly as I’d like. Sure, they could have done more with bypass capacitors and ferrites and things to get rid of the leftover fast switching noise, but any load you’re likely to connect will likely have its own supply caps or not care, or you can take steps to deal with it. The output is WAY more clean and stable than many a typical “wall wart”.
Neither of the output rails is tied internally to the centre ground connection (which I assume is tied to mains/supply ground). I.e. the output is floating. It’s worth noting that the output becomes somewhat smoother if you ground the -Ve side.
The output posts are screw clamp types but quite thin and lacking the sideways hole for wires that many of these types of posts have. The external part of the post is only about a 5mm diameter despite having a 4mm hole down the middle to take banana plugs. If that bothers you enormously then I daresay they can be replaced with better posts. (They mount with what look like 4mm screws with nuts on the back and should be easy to change.)
The supplied croc-clip cable for the load side is OK but thin, cheap-n-cheerful, I doubt mine will see any use.
The unit is light, but not as “tiny” as some reviews suggest – it’s not big, though. The dimensions are given in the description. If you stacked six standard DVD boxes together and stood them on their long edge they would be more or less the same size as this unit.
I have not tested the over-current protection, nor indeed its ability to supply the rated current. Mine allows output voltage to be set to 31v and current to 10.2A (I bought the 10A version, which at time of writing was about 14 more than the 5A one).
The build quality seems really good, and it’s noticeably fuller-featured than I was expecting, what with the system setting options and the optional serial comms remote control module (OK, I have no idea how you could get one but I’m willing to bet it’d be easy to hack a DIY one after a bit of a poke around inside. The facility to remote-control up to 32 of these from a single serial interface must be handy for someone!)
[update] I have now had a quick look inside to see if extra suppression could be installed, and it’s as neatly made as shown in the photos. The earth connection from mains inlet through to the ground post on the front is reasonably convincing, taking in various fairly generous ground planes on the main board via a couple of metal mounting brackets which appear to be meant to also ground the metal case. However, the powder coating on the inside of the case meant the case on mine was not in fact earthed. I scraped the coating off around where one of the brackets sits so that the case on mine is now earthed. When I dismantle it again to try to improve noise suppression, I’ll also scrape the case around the other earthed bracket, replace the terminal posts with better ones and probably uprate the output and ground hook-up wires.
This review is way longer than I originally intended but overall, I’m pretty impressed with this thing.
La compr de 10 ampers la proxima que compre sera de 30 Amh para completar esta
Contenido:
– Cable de alimentacin de CA
– Cable de salida de CC con cocodrilos en el extremo
– Manual de instrucciones (no incluye el castellano)
– Fuente de alimentacin
Diseo: la verdad es que no hay pegas en el acabado. La carcasa es metlica, sin artistas. Con un display en la parte delantera, con diferentes colores y en el que se ven todos los indicadores perfectamente. En la parte trasera tenemos un ventilador y el conector para el cable de corriente alterna. Los botones del panel frontal funcionan sper finos. Tiene 4 patas de goma sobre las que se apolla. No es muy pesado ni voluminoso.
Funcionalidad: de entrada comentar que tiene un adaptador en la parte trasera para configurarlo para funcionar con corriente alterna de 115V o 230V. En Espaa lo hemos de dejar en 230V.
Tenemos un botn que regula el voltaje y otro que regula el amperaje. El voltaje mximo segn especificaciones son 30V, aunque a m me llega hasta 31V. Y el amperaje mximo es de 10A. Por ende tenemos una potencia elctrica mxima de 310 W. Cuando ya hemos hecho la eleccin de nuestro voltaje y amperaje hemos de pulsar el botn output para activar la salida de corriente. Si giras tal cual las ruedecillas va cambiando decimal a decimal y entonces es lento llegar de un extremo a otro de los posibles valores. Si pulsas la ruedecilla va alternando el dgito que se va a cambiar de manera que puedes cambiar el de ms a la izquierda y por tanto llegar antes a los valores de los extremos.
Lo que ms destaco:
Los valores son bastante precisos y se corresponden con la salida real, tal y como podis ver en las fotografas y en el vdeo conforme lo he comprobado con un tester digital.
El puerto USB de carga que incorpora en el frontal, efectivamente es de carga rpida tal y como podis comprobar en una de las fotografas que he subido.
Incorpora un sistema de proteccin contra cortocircuitos (OCP) que se activa pulsando durante unos segundos las ruedecilla de regular el amperaje. Cuando est activado si en el elemento al que suministramos corriente hay un cortocircuito la salida de corriente se desactiva.
Lo que menos me ha gustado:
Los cables de salida son bastante justitos. Hubiera estado mejor unos un poco ms largos y con conectores de banana
/ Relacin calidad/precio: su precio son 85 euros. He encontrado fuentes de alimentacin regulables de 10 A a un precio ligeramente inferior. Hasta unos 23 euros menos. Eso s con un diseo ms feo y peores acabados. Sin proteccin ante cortocircuitos y con USB de carga de menos Wattios (el de esta es de 18W)
Espero que te hayan resultado interesantes mis explicaciones, vdeo y fotografas y si estabas en duda sobre comprar o no el producto te haya ayudado a decidirte.
alimentatore da banco compatto, leggero, con il quale non avere troppe pretese. se non si cerca la precisione al millivolt o milliampere va benissimo. provato a circa il 75% del carico (24v 7,5A) per alcune ore ed ha funzionato costante e senza problemi e con i parametri impostati.
Fuente de alimentacin de corriente continua capaz de dar hasta 30V y 10A.
Es muy compacta, su tamao es de 21.5 cm de largo, 15 de alto, y 9 cm de ancho aproximadamente, incluyedo las patas y los potencimetros del frontal.
La carcasa es metlica y la base tiene patas de goma antideslizantes, en la parte de atrs est el ventilador (no es muy ruidosa) y en el frontal est la pantalla, y los potencimetros de ajuste de voltaje y corriente, el interruptor de encendido y de salida, y los terminales positivo, negativo y tierra, adems de un conector USB de carga rpida hasta 18W, que podemos usar para cargar dispositivos.
La pantalla es muy ntida y de fcil lectura, con los dgitos en color rojo sobre negro.
Los potencimetros se pueden pulsar, para ir cambiando de dgito, as podemos hacer el ajuste de forma precisa y ms rpida que simplemente ir subiendo y bajando, ya que al ser incrementos muy pequeos, te eternizas.
La regulacin es muy precisa, permitiendo adaptar la salida a cualquier dispositivo que funcione en esos rangos.
Incluye cables de alimentacin, y cables con pinza de cocodrilo.
Me ha gustado, muy til si te dedicas a la electrnica, profesionalmente o simplemente como hobby, como es mi caso.
ottimo acquisto leggero e completo forse meglio la versione superiore da 10A.
For one thing, the LEDs are very clear and easy to see. And especially the white color makes it look more modern than the typical red ones.
The output button is a genius, it simplifies switching the UPS on and off all the time. This makes it very convenient.
Unfortunately, the power supply I received adds high noise/ripple to my circuits compared to the smaller power supplies in between 100 to 200mVp-p. I have already inquired with the manufacturer and am still waiting for a solution from them. I hope I can fix it soon, as I love the equipment.
After the recommendation from the manufacturer, I added one 2,200uF (30V) Capacitor and some Ferrite suppressors on the (+) and (-) terminals. This helps to reduce considerable the matter with the noise and the ripple (now is about 25mV p-p) . Now I am using the Power Supply without any inconvenient.
I fully recommend it. Actually I bought another for my projects.
Me ha sorprendido gratamente esta Fuente de alimentacin.
Tiene un tamao compacto, por lo que no ocupar demasiado espacio en tu escritorio de trabajo, o de pruebas.
Tiene una pantalla que te informa acerca de los voltajes de salida, estos valores tienen 4 dgitos, para dar una lectura ms precisa, ya que 2 de ellos son decimales.
Esta fuente de alimentacin es variable, por lo que puedes hacer casi cualquier prueba que requieras desde casa.
La potencia mxima que te puede otorgar esta fuente de poder es de hasta 300W, la corriente de salida tiene un mximo de 10 A y el voltaje puede ir hasta 30 V.
Su uso es realmente sencillo, en especial para quienes tienen experiencia en el rea. Contiene algunos puertos para colocar las puntas de prueba, y tambin tiene un interruptor para apagar o encender la fuente de poder de forma rpida.
Su peso es de poco ms de 1kg, as que se podra transportar con facilidad hacia otros lugares.
Fuente de alimentacin de dimensiones reducidas y poco peso, perfecto para tenerla a mano
De diseo chulo y materiales decentes, tiene una pantalla bastante maja
Tiene un puerto USB perfecto para cargar aparatos electrnicos
Viene genial para comprobar el consumo de energa, ya sea un electrodomstico o un vehculo.
El pitido que emite cuando se cambia los valores se puede quita
I was initially sceptical as to how one could adjust the voltage, current limit and voltage limit with just two knobs, but the knobs have switches incorporated that you push to change modes, so it’s dead easy to use. When not indicating these setting, the display shows the actual voltage and current being delivered. You can adjust the settings with the output on or off. It remembers the settings when powered down and returns to those settings when power is reapplied, APART from the output enable, which is automatically off after power up – a perfect combination. (The USB output is unaffected by the output enable button and is always on.)
There is one minor niggle – I would have preferred the positive output connector on the right, but it’s well indicated, so hardly a major problem when you get used to it.
The only real negative is that there is a fair amount of (electrical) switching noise on the output. I measured about 200 mV. p-p at about 40 kHz. on my oscilloscope. That is enough to upset some logic circuits, but is easily suppressed with a couple of ferrite cores on the lead to whatever you’re powering.
La fuente de alimentacin tiene un diseo compacto y cmodo de colocar en cualquier rincn de la mesa de trabajo. Dispone de cuatro patas de goma para una buena sustentacin y aislamiento. El cable de alimentacin es de doble clavija para guardar aparte de la fuente y tiene toma de tierra. La botonera de la fuente son de fcil manipulacin y giran con posiciones prestablecidas para una total exactitud de la medida deseada. La pantalla es grande, con fondo oscuro y de un gran contraste de los dgitos para su buena lectura. El cable de conexin para el dispositivo se sujeta mediante unas pletinas que se atrapan en las conexiones mediante tornillo de rosca con una pinza de cocodrilo forrada de goma en cada cable. Cuando se enciende y empieza a trabajas no hace nada de ruido, nicamente se escucha la corriente de aire que genera el ventilador cuando se activa. Puede entrarle corriente a 110 o 230 voltios. La salida llega hasta los 30 voltios hasta 10A y una potencia mxima de 300 vatios. Tiene fusible alojado en la misma entrada de corriente y el conector de USB va muy bien para cargar cualquier dispositivo mvil. Viene en una caja de cartn sencilla de color marrn pero con unos buenos separadores de espuma blanca para amortiguar los golpes. El folleto de instrucciones y caractersticas est slo en ingls.
If I was to complain about anything, it would be the supplied PVC coated wire terminated in spade connectors. I quickly replaced these with more flexible 14AWG silicon wire and banana plugs.
He estado unos das probando esta pequea fuente y sinceramente para empezar a moverte con garantas en los mundillo de la electrnica es un excelente aparato, ms que suficiente para la mayora de aplicaciones que le puedas sacar en el hogar, como probar pequeos electrodomsticos, mviles, yo por ejemplo le he estado dando caa probado mejoras para lo coches de radio control, la verdad que las aplicaciones de un cacharro como este en cualquier talleruco casero son infinitas.
Se trata de una fuente muy compacta de unos 20x15x8cm, con carcasa de chapa y hasta el cable de alimentacin se ve de una clida excelente, y puede suministrar una potencia de hasta 300w, 30v X 10A, su manejo es de lo ms sencillo y con 4 dgitos va sobradisima de precisin para las aplicaciones de ms precision.
Por supuesto cuenta con proteccin contra cortocircuitos, muy fcil de activar o desactivar, y corta la tensin en caso de fallo.
Donde recanea un poco es en el tema accesorios, que nada ms nos trae un par de cocodrilos con 5cm de cable y dos conectores Y, as que te tocar hacerte con unos vuenos cables, a poder ser con bananas, el conector y es muy incmodo de usar por estar muy abajo las tomas en el frontal.
En fin, personalmente me parece una excelente compra, salvo por el tema de los accesorios, por lo dems, una compra de lo ms recomendable.
Es una fuente de alimentacin DC genial. Si te gusta jugar con electrnica es una herramienta indispensable que te facilitar mucho la vida. Yo en el pasado me he hecho mis propias fuentes de alimentacin DC con kits DIY y han estado bien pero es un gusto tener un dispositivo tan profesional y completo como este. Si sabes mnimamente lo que haces, es virtualmente imposible que daes el circuito o dispositivo que ests testeando o esta fuente de alimentacin.
Me parece que el precio est muy bien para lo que es el aparato, la funcionalidad que ofrece, y la calidad de los componentes (lo he abierto para revisar) y la calidad de materiales y acabados de afuera. Se ve, siente y funciona como una aparto muy pro.
Como menciono, por dentro tiene componentes de buena calidad, ninguna baratija, todo SMT (excepto, claro, las resistencias y tal, que son lo que tienen que ser). El PCB bien est bien diseado y bien hecho. Todo muy ordenado dentro y soldado profesionalmente. En impecable: no hay ninguna evidencia de un trabajo hecho a medias. No hay cola o resina por ah, nada. Es decir, me ha sorprendido mucho por entro dado el precio. Adems, tiene muy buena disipacin de calor sobre el circuito en s, y eso aparte del ventilador que tiene. Por lo que el ventilador est apagado la mayora de tiempo y solo se encender cuando sea absolutamente necesario por alcanza temperaturas muy altas.
Como digo arriba, es virtualmente imposible que daes este aparato. Lo primero que hice, evidentemente, fue probar hacer cortocircuito y la respuesta de la fuente fue exactamente la que te esperas. He probado tambin invirtiendo la polaridad, y me ha sorprendido que eso no haya daado el circuito que estaba probando.
Vale la pena leer el manual antes de usarlo ya que, aunque no es complicado, para sacarle todo el provecho es necesario saber que existen ciertas funciones y lo que significan ciertos mensajes que te pone en pantalla.
La pantalla que tiene es grande, se lee fcilmente, tiene una iluminacin alta que se ve sin problema incluso bajo luz intensa, y te dice lo que necesitas saber.
Por ltimo, la inclusin del puerto de carga USB me ha parecido un plus muy bienvenido y til, pues es algo que siempre viene muy bien.
He quedado muy contento con esta fuente de alimentacin y ya la he usado varias veces para varios proyectos, en los cuales ha hecho una gran diferencia en trminos de practicidad. Como ha comentado un comprador, me hubiera gustado pillar la versin de 10A en vez de la de 5A, pues me ofrecera mucha mayor versatilidad en lo que me gusta hacer. Pero como tampoco lo hago profesionalmente, pues la verdad que para la mayora de proyectos pequeos que hago la de 5A basta y sobra
– El claro indicativo de si estamos en Tensin Constante (CV) o corriente constante (CC).
– La precisin (la cual no aumenta del 1%).
– La facilidad de uso (con los botones justos y necesarios).
Como pega, le puedo poner que tarda aproximadamente unos 5 segundos en actualizar los valores en pantalla. No me refiero a la salida real, sino en lo que tarda el display en mostrarlo, ya que en la salida es casi instantneo.
Tambin debo destacar que recomendara tener pinzas de antes, ya que las que viene son para salir del paso. Personalmente yo he preferido usar las mias de entrada banana, antes que tener que desenroscar continuamente las que vienen; pero eso es un defecto externo de la propia fuente, no influye en nada respecto a su funcionamiento.

Tambin est equipado con funcin de proteccin contra cortocircuitos OCP. Para activar la funcin contra cortocircuitos, solo hay que mantener pulsado el botn “corriente” durante tres segundos y si el OCP est encendido, eso significa que est activado y si est apagado es que est desactivado. Cuando est activado, apagar la salida si el producto que se est probando tiene un cortocircuito.
Una buena fuente de alimentacin, ideal para utilizar en reparaciones de telfonos mviles, ordenadores, carga de bateras, etc. Decid cogerla para su valoracin porque a mi marido le gusta mucho enredar y reparar aparatos elctricos como mviles, ordenadores, tablets, etc., y la verdad es que le est dando mucho uso desde que lo tiene, y apenas lleva una semana usndolo y me comenta que es lo mejor que he podido conseguirle, est muy contento con la fuente de alimentacin.
Relacin calidad/precio muy buena. Mi marido estuvo en tiempo mirndolas para adquirir una y las haba visto ms caras y de menores prestaciones que esta, por lo que puedo asegurar que esta, tiene una excelente relacin calidad/precio. La recomiendo.
Espero que mi valoracin sobre el artculo haya sido til para resolver tus dudas.

As of 16/02/23 this product has 48 global ratings, with 4.6 out of 5. Of the 48 ratings 28 are reviews. Of the 28 reviews a substantial amount (9) of these are from reviewers who have the status: ‘Vine Customer Review of Free Product’, where all, bar 1 gives 5 stars. The 1 remaining gave 4 stars. Of the Vine reviews, there are a handful that are just simply quoting the specs and showing off what it looks like, rather than how it performs or what they intend to use it for.
I’m only mentioning this so that people are fully aware that nearly a 1/3 of all reviews are from reviewers who have had the item gifted for a review. The cynic in me would think positive reviews perpetuates free products…
My Review
=========
Build: On initial use the product itself is actually very good. Granted I’ve only had it a couple of days, so I can’t comment on longevity. However, the build quality is great, with it being as small and as the photos show. It’s nearly 1/4 the size of my old power supply. Speaking of my which, my old power supply still works, but the fan kicks in on power-up, whereas the fan for the new device is off until there is enough current being pulled for it to warrant coming on to dissipate heat. So, for noise, the new power supply wins as it is whisper quiet.
Design: I like the move away from the traditional red-on-black text displays to white-on-black. While it’s a little clearer it just seems more modern. Same with the body colour, moving from white/beige to black. I know these are minor points for something that is a functional device, but I think it’s good design progress.
Usability: I think the USB port on the front is another bit of progression, as it lets me power a USB-C soldering iron.
The adjustment knobs have a slight indentation feel when rotating, so it feels positive when selecting the voltage / current, and so less likely to waver.
Gripes: I don’t like the fact that they give you test leads where they’ve attached / chosen u-type connector, rather than banana plugs. They are a faff to take on and off, and add concern; especially as one reviewer has already stated that one of the posts has broken off.
As 2 other reviewers have pointed out, the power cable fitting is not as snug as it should be, so I’ll need to see if the cable connector needs a piece of insulating tape to bulk it out. I don’t intend on moving it much, so I’m not sure how much of an issue it’s actually going to be, just a bit of annoyance at the moment.
While the build quality is good, the price is a little more than I was expecting to spend – 74.99 plus a 5% discount, taking it to 69.99.
Accuracy: I never hold out much hope for these sorts of products in terms of accuracy. They tend to serve a purpose and if I wanted absolute accuracy then I’d have to spend a lot more. That said, I tested this unit at 10v, 12v and 15v with two different digital multi-meters and the figures were, pretty much, spot on. 10v came out at 9.99v and 9.98v, depending on the DMM. 12v was 11.99v on one (forgot the other). And 15v had 14.98v on both DMMs. Good results.
Use-case: while I’m not the most tech-savvy when it comes to electronics, I do like to mess around with different electrical components/devices, such as ESP8266/32, WS2812b LEDs, 3D printers, etc. So, I make use of my old one a fair bit, but just had been put off by the noisy fan – particularly annoying when I went through the task of replacing the fans on the 3D printers as the old bench power supply would drown out the new fans! If only I’d have bought this a bit sooner, I would have saved myself the hassle of having to daisy-chain test leads to move away from the noise.
Display is easy to read – the figures are well-lit and large enough to see, even in the dark.
You can set the parameters of the power supply yourself quite quickly – you have a good level of control over this.
It even has a USB port that supports Quick Charging. Can be one alternative if you don’t have a normal wall charger that is capable of this.
It wasn’t as heavy as I thought it would be either. It can be easily carried around from room to room.
A very decent desktop PSU. Mostly metal in construction. Great display that is viewable from all angles. Fine thread terminals that grip well. Easy tuning of the output required using the two knobs. Only slight annoyance is the beeping on every step change! Quality of the internals is excellent too. USB charging is handy but I couldn’t test if fast charging works because my phones don’t support whatever tech the PSU supports.
Instructions are reasonable English. It covers the WPS and APS models with the APS seemingly offering far more functionality (presets and PC communications).
My only problem was that mine kept turning off. The problem is the IEC plug on the mains cable that is supplied doesn’t fit the PSU socket very well resulting in a failing connection. Changed the cable and problem gone.
Quite pricey but the quality is good so it’s worthy.
Apparently Mr Frog has been itching for one of these for a long time, so when the opportunity arose to test it, guess who jumped!
Much smaller than I expected — but what I know about these things could be written on my tiniest finger nail — it is exactly what he expected, so that’s a good thing.
Small, quite light and very well made this looks impressive even to me who, as I said, knows nowt. He could wait to show me all the possibilities with it, so I stifled a yawn and stood patiently (not)
It has a really clear, bright display panel and lots of knobs and things. Ah — is that a USB output port I spy? Now that I understand — so it’s a powerbank? Yes, apparently so. The main purpose is for Checking Things. I didn’t ask. However, the lesson had not finished, as Mr Frog dragged out various bits and pieces for demonstration. I tried not to let him see my eyes had glazed over…as I heard words like Voltage and Current and Output floating through the air.
So, the verdict is — this is brilliant-just-the-job-so-excited-can-do-all-sorts-of-Stuff….
Well made, well designed, he’s pleased, I’m pleased he’s pleased….can I go now?
Car Battery charging, needs to be used carefully for that but it does work for that purpose.
I am so amazed with this….it’s so little….but so strong. Amazing metal case. I like the fact that it’s adjustable…you have a good range from 0-30V and from 0-5A….which is amazing. I love the fact that it has a USB output …so i will definitely find something to charge with that. I mostly wanted this to power up smal projects that i have in my garage…which it did and i am very pleased with it. I also use it to charge batteries….so…overall…i am very impressed and very pleased with it…..and IT’S WORTH THE MONEY…definitely. You won’t regret buying it.
This unit is the perfect size to fit on any bench, its extremely easy to setup and use. I have tested the output voltages using a volt meter and they are very accurate. All in all i give this unit a 5 out of 5. Perfec
I’ve been happy with this power supply. This power supply is pretty light weight -wise and Easy to use. works great for my ham radios. The voltage output was off by less than 0.1 volts across the range vs the reading on my multimeter. So far It has been a very good unit and has charged several different batteries and battery types. I even used this to recover a dead battery that was reading 0 volts. Also I really like the ability to set the current limit as this gives me the capability to charge various types of new technology batteries as well as power my projects and USB port will be handy to charge various devices on my desk.
Clear 3-line LED display and a good compact size. Capable of displaying voltage from 0.01v and amps from 0.001A. The power supply can output USB using fast charging at 18w. The power supply can accurately set the voltage and current you need, and it can automatically calculate the output power based on the output voltage and current, while displaying the voltage, current, and calculated power on the screen. In addition, it can be switched between 110v and 220v so ideal for all markets. Also have peace of mind in knowing that it has over-voltage protection, over-current protection, over-temperature protection and short-circuit alarm to stop the output.
Overall, very impressed and the metal casing oozes quality too!
Thank you for reading.
This is an exceptionally good power supply. Small, quiet, very easy to set up with a button output control to make things easy when testing potentially sensitive bits of kit, Has a power measuring function! How good is that. You can then chose a suitable fuse to protect your bit of kit when you transfer to a dedicated power supply. Fantastic!
I used the Mini high Precision Bench Top PSU to test a CCTV camera , the camera required 2.0 amps at 12v to power the camera , it was easy to use the voltage adjustment dials to set the correct voltage and it was displayed on the units display which was easy to read.I could then use the onscreen display to see what the current that was being drawn by the camera which was also displayed on the units display so all the information I required was at hand.
After a week on soak test the PSU is still outputting the correct voltage that was set when I first set the voltage up to connect the camera and the camera hasn’t reported any power issues while its been tested.
This is an ideal addition to my workshop as it saves me messing round look for different PSUs for different equipment , with this PSU it does it all
Una fuente conmutada de tamao compacto, perfecta para iniciacin a la electrnica o para usarla como fuente auxiliar.
Es idntica a otras fuentes de este tipo, con conexiones de salida a banana y ajuste en tensin y corriente.
Los cables de alimentacin de salida no tienen terminal de banana, sino unos ms baratos con terminales en U (no le costaba nada al fabricante poner unos ms universales, la verdad).
En algunos casos es probable que necesites una fuente de alimentacin regulable con transformador (por el tema de ruido elctrico), pero en la mayora es probable que te baste con una conmutada como esta. Consigues potencias de salida bastante elevadas para el reducido tamao de la fuente.
Si la vas a usar para una tarea que no sea crtica, est bien.
Why would you want a variable power supply like this one? You must have your reasons, or you wouldn’t be reading this. In the right hands, these power supplies are indispensable. For me, it’s testing and repairing electronic items. The ability to current limit the output can save a lot of damage while tracking down the fault.
It arrives in a rather plain brown cardboard box. Inside is the power supply, a mains lead, a set of test leads, and an instruction manual. The manual is a bit confusing as it covers many models in the range, but all the information one needs is there, somewhere.
The model I received was the 30V/5A one. As its name suggests, it can output between 0V and 30V at up to 5A. The voltage is totally variable and adjusted using the voltage knob, and the voltage is displayed on the digital display. To aid quick setting of the voltage, you can press the knob in, and the part of the voltage display will start flashing. You can step through the digits by pressing again.
There are situations where you will need to limit the current that can be supplied. This is very useful if you have a near short situation and need to trace the fault. The current can be limited anywhere between 0A and 5A. If the current tries to go higher than this setting, then the voltage will automatically drop until your selected current is attained. Again, the currents are displayed on the digital display.
What is useful is that the digital display will also display the wattage being consumed. Although this is easy to calculate yourself, it does save a lot of time.
An unusual addition to this power supply is a USB quick charge type-A socket. Although it’s not stated, it’s actually QC 3.0 compatible and can supply up to 18W.
Overall, a very functional variable power supply for your money. I hope that helps.
I liked that one can disconnect the output by a button press, 10mv resolution and the over current protection.
Like: solid build, easy to use, good compact size, easy to change value volts/amps
Dislike: bleeps with every incremental change – bit it’s not that bad.

PRODUCT SEEMS TO HAVE GOOD BUILD AND FINISH. HAVE CHECKED DIGITAL REAOUT
WITH AVOMETER AND APPEARS TO BE WITHIN 0.5V OVER THE RANGE. THE OUTPUT
SWITCH REQUIRES A SHORT PUSH TO OPERATE OTHERWISE IT WONT WORK
Muy contento sinceramente. De lo nico que me arrepiento por el precio es de no haber comprado la de 10A, cuando le di a comprar no vi que haba esa opcin. Por lo dems me gusta mucho, por lo menos por el precio que tiene. Los acabados a mi me parece que estn muy bien, se lo ve bueno. Los valores que da son muy precisos. He probado a hacer cortocircuitos y responde muy bien. No se calienta nada, ni hace olores raros a chamusquina ni nada. La PCB me gusta porque mir otras y apenas tenan disipacin y mucho circuitucho pequeo, lo cual, todos sabemos que si vas a dar corriente, no es muy lgico. Sin embargo en esta tiene unos buenos transistores conectados a un buen disipador al que le apunta el ventilador en caso de necesitar encenderse. Si no se calienta, el ventilador est apagado. (99% del tiempo de uso) Lo dicho, muy contento.
Looked at a lot of other units and their reviews , with all of them having some bad ones .
This is simply to use accurate enough for what I require and well built.
Delivered the next day in well designed package always a good sign ,attention to detail.
Does what I need and I would highly recommend this unit for this price bracket . 5*.
I had a small issue and needed to ask their support a question, and they were very helpful and quick to respond and help me out. I’d buy from them again no question.
