Programmable DC Power Supply (0-30 V 0-10 A) High Precision 4-Digit Multiple Protection with PC Software and USB Charging

Bought as an upgrade from the internet auction special analog power supplies, as that one was frustrating when the input would drift. It's precise, easy to use (if not intuitive), the software is windows only and is mostly just a display, but it supports pyvisa so you can write your own python code to talk to it and do logging. Fan is noisy if you're pulling more than 50w, so bear that in mind, I might swap mine for a noctua or something similar in future. The quality inside is amazing, selastic on every connector, beefy high-rating capacitors, nice little serial comms board, and the screen print markings on the pcb. seem to indicate this is an owon product on the inside. It's not a lab power supply, don't expect it to be, it's noisy on the output and the polling rate isn't massively quick, about every quarter second from what I can tell. It's not priced like a lab supply though! Perfect for charging batteries, a bit of custom code logging, testing RC equipment, emulating other power supplies, and running small to medium electronics projects.

Worked. Easy to use. My needs are simple but it has a lovely display and I found it easy to understand.

I bought this as an upgrade from using a much older bench power supply, this is a third of the size of my old one and gives me much more power, I've been using it now for a few months and it's been really nice to use, really simple to dial in and change voltage output on the fly and the display really does give some truly useful information that's really made things so much quicker and simpler while I've been developing new ideas, the one thing I would say to watch out for is that when you power up these units from the switch at the rear which I'd prefer to see on the front it takes a few seconds to boot the screen up and once it does it switches on the output voltage automatically so just make sure your leads aren't touching or you don't have things plugged in that might be damaged when you power on, I'd prefer to see this switch on into a standby state but as long as your aware it's ok, I held back one star based on this issue otherwise I'd say five stars

Nice small size ,good price performs well, stable and accurate some low noise which may effect RF devices.

Perfect for what I need it for, does have a bit of noise attached but acceptable, unlike other cheaper psu that you have to short out the cables in order to use current limiting, this is directly adjustable in the display and it also has a disconnect function button, only issue is that as with other psu, it would be nice for the mains switch to be on the front

The graph of current and voltage over the last 60 seconds is a great feature and quickly lets you see what's been going on... very useful for problem solving. Pretty easy to use with all the functions you could want. The fan does get noisy once the power gets up, but that's to be expected with a compact device. The output voltage is also a little noisy, but not enough to worry about for hobby electronics.

Using it for some nickel plating projects, works great and the memory function is really useful.

Works well, the power supply UI is fine but the multimeter functionality could be improved. I wouldn't recommend it as a primary multimeter but good to have as a second multimeter when needed I was hoping I can analyse more detailed logs on my monitor. But it's only windows and even there it is very limited software

No soy un profesional de la electrónica, pero llevo años usando esta fuente para mis proyectos y para probar pequeños circuitos y sigue funcionando perfectamente, de vez en cuando voy midiendo el voltaje y el amperaje y debo decir que es bastante precisa. Para buscarle algún defecto, es un poco ruidosa, pero, para un uso ocasional, se puede soportar sin problema. En definitiva una buena fuente para aficionados y oara pequeños proyectos.

Belle alimentation pilotable et programmable même via PC. Elle est petite, pas lourde, mignonne et précise. Pour le prix c’est incroyable. Avec un petit écran qui montre de façon graphique ou numérique les infos. Juste pour info, pour le logiciel, il faut prendre le dernier logiciel pour que sa fonctionne et s’installe correctement. Le lien de téléchargement ce trouve sur la page du produit. Et après tout fonctionne comme une horloge.

Bien précise et stabil.....Nickel

以前7000円くらいで買った安定化電源から買い換えました。 買い替えポイントは、主電源とoutputスイッチが独立していることと、 設定値のメモリができること。 他にもOCPが使えるとか電流のグラフが見れたり、watが表示されたり、便利なところはあるけど、 なんかビジュアル的にクリームソーダみたいなミドリ色も好きです。 説明書きにも書いてあるけど、日本版にはCDがないとか、USBINが何をするのか、QRコードで APダウンロードは怪しいからやめました。 アプリってなにすんの？って感じ。 あと、レビューにも多いから知ってはいたけど、fanの音がうるさい。 レビュー見てどれくらいうるさいのかと思って買ったけど、半端なくうるさい！ 良く見るとFANも吸い込みで使われていて・・・気になったので、静音の2500rpmFANに 交換。ずいぶん静かになった。もううるさくない(笑) 私の場合は、使い方はほとんどワンパターンで、５V～24Vくらいの電圧で繋いで、その時に どれくらいの電流が流れているかが見れればそれ以上の使い方はしないわけ。 時には電流絞ってどうなるかとかやることもあるけど・・・ でも、見た感じでグラフが意外と使えると思いました。 それは、例えば、オーディオアンプの電源に繋いだ時、レベルを上げていくときの電流の変化や、 電圧降下なんかはグラフだと見やすいかも。 そんな感じ。なかなか良いと思います。 おススメ！

Klein en krachtig. Eenvoudig in gebruik. Het programmeren duurde wat langer door beperkte instructies maar het werkt zoals beloofd. Zeer goede recensies op youtube te vinden. Het enige nadeel is het lawaai van de koeling zodra je wat meervermogen vraagt. Ideaal om te experimenteren en knutselen met electronica.
