DC Power Supply Variable, 0-32V 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

A great small-footprint power supply for the money. The unit contains many useful features for a unit in this price range. It matches, or exceeds, the performance of many bench supplies I've used at 3 times the cost. Digits are large and easy to read, knobs feel tight and smooth, and the unit is solidly constructed. The output voltage readings are very accurate. The voltage tracked very precisely down to the second decimal place when tested using a Fluke 87 multi-meter. The voltage and current adjustment knobs are digital control and have small detents at each volt (Coarse), and each tenth or hundredth (Fine), which means no more analog cycling between digits. The English translation of the user manual is adequate, but left out information on one feature. The OPN (Output Power Now) feature was not fully described in the product manual. A quick search on Amazon's product page helped to define the function. To summarize, the feature lets you choose whether the unit immediately outputs the selected voltage when the unit is turned on, or whether it only activates after the "Output" button is selected on the front of the unit. There are definitely times when both of these options are handy. The cooling fan is temperature controlled and comes on only after a period with the power supply loaded. The fan seems to run at multiple speeds and produces very little noise. In summary - this is a great little addition to the workbench and seems to be a solid unit considering price and features. I look forward to evaluating its longevity, and I will update this review if anything changes.

Fairly rugged , metal enclosure, weighs enough to sit firmly on its rubber feet. Very nice front panel layout with sensibly spaced easy to use controls and relatively large & bright display that is easier to read from a further distance than many others. Output enable /disable button is an especially valuable feature and all buttons and controls seem to be of decent quality and work well, also they seem very intuitive to use, so it doesn't require a huge user manual but the one thats included does pretty well at explaining operation, although the manual included with mine does not explain the very useful OPN mode feature but fortunately that is briefly explained in the advertisement on Amazon. Only one other feature i've noticed isn't clearly explained in manual or on outside of packaging is the voltage range does n fact go up to 32V (at least on the one i received) just like advertised on Amazon but despite the "30" volt limit printed on the box or in the manual. Otherwise i like this supply very much and probably will buy another one, also i'll recommend it to others.

Was a little worried about buying a cheaper bench supply, but this one has worked out really well for me. Voltage and current readings checked out accurately against my multimeter and the controls are simple to adjust. Been using it for small electronics projects and LED testing and it’s been reliable so far. Nice having the adjustable current limit too when powering something for the first time. Overall it’s been easy to use and has held up well. No complants from me.

Nice power supply, small and light, unlike my old 20 lb monster! Easy to use, easy to adjust, regulates well. I love the feature that lets me shut off the output. The fan does make a bit of noise but this thing is meant for a work bench environment so no big deal. One star off for the awful 'hot' chemical smell it gives off. I have some sensitivities and this odor gave me an instant headache and nauseous feeling. I am hoping this smell is temporary and will eventually fade away.

This replaced a power supply from back in the 70s. The old one was "jumpy" to say the least. This one is spot on. Checked with a Fluke multimeter and a Siglent Oscope. Not a bit of ripple and accurate to the hundredth of a volt. I couldn't believe how it held the voltage no matter where it was set. And the next time you use it, the last setting is right there for you. I was drawing 8 amps on a 12 volt dc motor and the supply just was solid as could be. It's only a month old, so can't speak to longevity, but if it holds up over time, this is worth 10 stars.

Works well for me. Used it to bench test random electronics such as a standalone ecu or random stepper motors. Has a great amount of features too.

This device is the 3rd DC power supply I've owned and is by far the best, especially for the sub $100 machines. It's definitely got to be the easiest power supply out there to. Be advised that the cables are short so go ahead and order you some longer ones. They are the banana plug type. My multimeter showed about a volt difference so it's not ready for use by NASA but it's certainly good for me.

Great power supply for the price. I use it for my jewelry hobby, mainly for electroplating copper and it works perfect for that job. I did check the voltage output with my multimeter and it was accurately producing the voltage I had dialed in. Overall, I would recommend for this type of use as it is fairly light weight and seems to be built decently for the cost. The display is easy to read, as well.

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

Très bon rapport qualité prix

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.

他の電圧系で見ると０．０４マイナス表示でした.問題ない安定度でした。
