DC Power Supply Variable, 0-30V 0-10A Adjustable Switching DC Regulated Bench Power Supply with High Precision 4-Digit LED Display, 5V/2A USB Port, Coarse and Fine Adjustment SPS-3010

Consistent, stable power with sufficient capability to support somewhat higher amperage needs were key criteria in my selection for my bench supply. I use a bench supply weekly, but for sporadic projects and testing rather than any heavy or production needs. So cost was also a big factor. This Jesverty SPS-3010 30v, 0-10A adjustable supply was on sale and I was honestly skeptical as to what I would find at such a great price.The included instructions are light, but I had absolutely no problem setting, using and adjusting right out of the box. It is surprisingly light in weight making me wonder about the circuitry. I deeper look showed good quality caps and solder and overall construction.The display is very bright, and adjustments permit relatively fine settings. For the average need of power supplies in this price range this is a winner with regard to output and settings. The voltage remained stable and load balance was likewise good on the various tests I performed.One caveat: The "Coarse" adjustment knob is quite sensitive and landing on the general output voltage requires some fiddling. The "Fine" adjustment range is limited and is not always sufficient to make all of the adjustment if you are heavy handed with the coarse knob.It comes with two basic leads terminating in alligator clips that are flexible and clamp reasonably well. Standard jack size permitting numerous other cabling/clip options as aftermarket purchases. My old leads fit snuggly and work just fine.The only other item included was a standard power cable that is just long enough to allow convenient positioning on my bench. Since the supply is so light it is easy to move around for different projects which I hadn't thought of but really enjoy.The power needs that I typically work with are well within the specs of this power supply making it quite versatile and handy. There is a USB output as well and I wasn't sure I'd really have much need yet after working with this for a while now I find I'm often using it as I work to complete a project that is USB powered. Nice for testing too!Honestly, if this were to last only a year I feel I'd have gotten ALL of my money's worth. My guess is that this will last long in my environment, and it does have internal fuse protection.

I have been working in electronics for a while and for some reason refused to get a power supply… this changed my life. Reliable power and accurate measurement or current draw has been a real time saver. Feels very rugged, and I like the layout of the knobs and screen. Only with the knobs were less sensitive at the bottom end.Love it.

For the money it's good, but know what you're getting here.This power supply is most definitely NOT in the same category as my 30v programmable power supply that cost me >$300. In that regard it lacks a LOT of features, you can't just preset everything prior to connecting the load, and you can't set stuff like voltage ramps, timers, USB data interface, etc. If you're used to working with higher end regulated supplies, this unit will throw you for a loop initially.For the price though it's surprisingly not bad though!Like I said I already have a really good high end 30V regulated power supply with a lot of bells and whistles, but I needed something that could put out at least 40V which is why I bought this 60V supply. I didn't need all those features that my other unit has just for this task and I didn't want to spend a ton of money on it either. For that it gets five stars.I took a star away because of the way you preset the amperage (set voltage to no more than 5V and then short the leads together). Does it work? Yes. LOL. Not the most elegant method out there but it is what it is. I'm just imagining the leads glowing red hot because someone with less experience doesn't double check the voltage first and leaves it set too high before shorting the leads. LOL.The voltage displayed on the interface is pretty spot on, at least according to my meter.The dials are a bit touchy but once you figure them out they work fine. Again this is a very inexpensive 60V regulated power supply so you're not going to get things like dials that have notches in them so you get some feedback when you turn them.One thing that confused me at first is that there's no on/off switch for the output (just for the entire unit). When you hit the main power button the unit puts power on the leads. There's no way to stop the power other than disconnecting the leads or entirely powering off the unit. I know that's something I'm used to having on my more expensive unit, but it'd have been a nice safety feature even on this lower cost PSU.If you just need an inexpensive regulated power source that can go up to 60V, this will most definitely fit the bill. For that it's excellent. Beyond that it's rather no-frills though, but the price is most definitely right as long as you know what you're getting for your money.

Very seldom have I received a product that preforms better than expected. This 30v 10a power supply is one!!I'm 65 ,worked in electronic most of that time. 🤔 I'm amazed that I finally purchased a item that is such top quality.

Works to replace an OVER PRICED Husqvarna 450XH Automower Charger that Failed. But I can't tell you the steps to make it work for that. I needed an electrical engineer son, to assist. Otherwise, would've had to shell out eight to ten times more money to replace the Automower Charger.

The media could not be loaded. I purchased the 120V, 3A unit.My unit is pretty accurate - certainly more than I need for my use cases - testing triacs, diacs, trigger circuits, etc. I needed somewhat high voltage for testing certain components like DB6 diacs (typ. 60V).I usually see up to 10mV of tolerance - sometimes up to 20mV, and sometimes spot on. I have no idea if the operating tolerance of mine would be the same as yours as I only own one, but I am happy with the performance for the price.The external build quality is fine - nothing special but the display is nice and is easy to read.The knobs move quite quickly, and the one suggestion to the company I would make is to have slower, more precise voltage movements with the FINE adjustment knob. If you need very fine, precision adjustments, this unit may challenge your patience. If you don't, this may be the unit for you

Works perfect for my use.
