DC Power Supply Variable, 0-30V 0-10A Switching Bench Power Supply with 20W USB & Type-C Quick-Charge, Encoder Corase & Fine Adjustment Knob, Output Switch, 4-Digit LED Display - SPS-3010V

30V at 10A variable power supply with current overload detection. The large white LED display was easy to read even in strong daylight. The case is made of aluminium and should be rugged enough for regular home workshop use. The vertical layout is great, leaving more room for other equipment on the bench As well as testing on some low power PIC breadboarding stuff, I also tested the unit on some low-ohm power resistors and the PSU performed well over its specified range. Output was steady with very low ripple on the output. The rear fan was quiet enough to avoid being annoying. I really liked the combined Volts/Amps/Watts display - brilliant for testing VI characteristics and matching components without reaching for a calculator. Looking at the internal PCB through the vent slots reminds me of a PC power supply and to be honest this unit is physically not much bigger than one. Included with the PSU were a pair of short power leads terminated with crocodile clips and standard banana plugs. There was also a mains power cord provided. At just over 1m long, it was way too short for my bench but should be adequate for most users. The paper instructions were clear, but I must say, getting used to the encoder-type rotary controls took a fair bit of time for me. I kept reaching for the coarse-voltage control by default and overcooking my test circuit. I think it would be much safer if the rotary knobs were variously coloured instead of all black. I reckon the 'output-enable' pushbutton should be coloured too. The overcurrent detection feature was very useful... Once I figured out how to set it up. Apparently, the PSU can also operate in 'OPN' mode which bypasses the ouput-enable button. However I never intend to use it, preferring to use the manual ouput-enable button to avoid potential circuit fry-ups. Overall, a really good bit of kit which provides plenty of bang for buck. Small and mighty. The all black look is cool, but perhaps impractical. I reckon a splash of colour for the buttons and rotary controls would make operation safer and even easier. Highly recommended.

Works a treat had it a while it’s working great.

happy with the product, sturdy and reliable and good price

have owned for 3 months now great reliable product

Quality bench power supply. Recommend 👍🏻

Not had chance to use it much yet but seems a good bit of kit.

Compact, reliable and very stable output. Easily adjusted voltage/current and very much a "plug-and-play" solution at a reasonable price. USB-A and USB-C sockets make it easy to connect items for charging. I haven't put the unit under great stress and, as yet, the cooling fan has not been used, so for me the unit has been silent. Attractive and clear display

small little bench psu good for a hobbyist

初心者でよくわからないが、 安価なソーラーライトに安価なBMSを追加するのに、 BMSが本当に動作しているのか気になって購入。 無事動作確認が済んだ。 （BMS：アマ購入1/10不動。アリエク購入3/10不動。） Type A端子がズレてて硬かったので、常に接続してクセをつけている。 どのくらいの負荷でファンが回るか分からないが、 回っているところはまだ遭遇せず。 でも、初心者には使いやすかったし、 何度もOCP機能に助けられた。 ソーラーパネルとLEDの間の配線を延長した時に、 どのくらいの太さのコードで、何mでどのくらい降圧するかも簡単にテスターでみれて良かった。 レビューにあったコンセントコードの接続は問題ない個体だった。

Nice, testing Peltier build with the variable voltage and current. Connection can be wanting though.

I was initially considering an alternative power supply with four memory buttons, but that model lacked USB ports. As a result, I chose this one instead. Pros: * Aluminum housing: Durable and gives a premium feel. * Compact design: Fits easily on a desktop without taking up much space. * Intuitive knobs: The coarse and fine knobs for voltage and current adjustments are excellent. Each step is tactile, making precise adjustments easy. * Quiet operation: The fan remains off under light use and only activates when cooling is necessary. * Versatile USB ports: Both USB-A and USB-C outlets are included, making it ideal for powering Arduino projects and other devices. * Flexible power terminals: The combination of a banana jack and a screw mechanism allows you to either plug in test leads or secure a wire by tightening it. Minor Cons: * Button quality: The OCP and OUT push buttons feel slightly wobbly. * Lack of memory buttons: While not a major issue, it would be great to have memory buttons for storing settings in future models.

Finalmente un ottimo alimentatore, va oltre i 30 Volt e oltre i 10 Aper leggerissimo ma fatto bene anche a bassa tensione è possibile prelevare i suoi 10 ampere ed è molto preciso ovviamente si consiglia degli ottimi cavi in uscita per evitare surriscaldamento, la ventola poco rumorosa va in funzione solo ad una certa temperatura per poi fermarsi e con i suoi display in bella vista in cui ti dice tesione amper e watt e due prese per la ricarica USB- A e USB- C fanno di questo alimentatore un pezzo molto valido e così ne ho preso un'altro in modo da poter lavorare anche nel box , lo straconsiglio.
