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.

Great unit and works as advertised. Great sensitivity on the Volts and amps

I like this very much! I use it every day, all day as a two way radio repair technician. The display is great, very accurate, stable, great features. On my bench for many months, flawless!

If I just knew how to adjust brightness of the white display (assuming it can be adjusted like stated in the ad) I'd give the seller 5 stars. So far I've looked around and found brightness adjustments for other of the Jesverty models but not the one I bought. Oh well, I just have to pause a moment when looking from the supply display to breadboard so my eyes can adjust. Mind you the brightness is not an issue in a well lit setting; but during times I let the project run late into the evening is when I wish I could turn the brightness down. One other negative is the output jacks do not have the small thru hole which would allow putting a bare wire into the hole and then snugging down the jack onto it. Thankfully I bought a set of banana plug cables with alligator clips on other ends. That was pretty much the only problems I've had with the Jesverty power supply. Everything else is working just as advertised. I have sometimes wondered about having the coarse/fine knobs for volt/amp settings. The coarse setting alternates between the two left most digits while fine alternates the right most two digits (beware! If you do this adjustment with either volts or current below 10.00 you will be changing the tenths digit rather than only the ones or tens position) For example I planned on changing the amps coarse setting of 1.500 to 3.500 and the indicated position being changed was the tenths so I went 1.6, 1.7, etc rather than 2.5 and 3.5. Pay attention to the highlighted digit when making adjustments. I like the output power on/off function so I can make adjustments w/o having to disconnect the power leads. I also appreciate having a watt reading in the display - I won't be grabbing the calculator nearly as often. I have noticed the watt reading changes with voltage or amps so I suspect it may be a calculated value rather than actual. For instance when charging a battery the amps will constantly be changing yet the watt display doesn't pick up on those minor changes unless there's a change to volt/amps of the display. I guess it's too much to ask for millvolt level displays with a switching power supply; but I frequently work with very small adjustments such as 2-5 millivolts. Granted the display shows 0.001 for millamps so would be nice if the volt display would switch to 9.999 when working below 10 volts. Of course the display is well filtered so you don't notice the ripple of the power supply output - the spec value of <0.5% Vp-p is consistent with what I saw on peak reading of Fluke 87 mulitmeter as well as o-scope. No real surprises there. The USB-A and C outputs are both limited to 20 Watts or 5 volts at 3.6-4.0 amps from what I've found. I haven't tried to see if the USB-C output will support any of the other possible voltages - documentation for the supply doesn't say anything either way. In the future I plan to get a couple USB cables with cut off ends so I can use the 5 volt output for electronics projects while at same time using the regular output for 6-15 volt needs. The fan is temperature driven so in my low <200 watt testing I have barely noticed the fan operation. I imagine it could be somewhat noisy once the supply is providing >500+ watts but that's not something I've been able to check. I'm quite pleased with the Jesverty power supply. It should work well for general ps needs and the price/quality has me very satisfied with this purchase. A good buy in my opinion.

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.

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.

Great power supply. Used to charge car battery. Definitely great value for the price

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.

かなり前に購入したものが壊れて、購入してみました。 細かい設定・出力ON/OFFは便利です。進化してました。表示もみやすくGOOD ジャンク系・モジュール系大好きな私には、必需品ですので毎回使ってます。 電源供給・あらゆるバッテリーの充電・実験用にと用途が広いのでほんとにありがたい一品です。
