DC Power Supply Variable, 0-120V 0-3A Adjustable Switching DC Regulated Bench Power Supply with High Precision 4-Digit LED Display, 5V/2A USB Port, Coarse and Fine Adjustment SPS-12003

I tried it out running 100 V at 1 amp into a resistor, and the voltage on my DMM agreed within .1 volt of the meter on the panel. Also switched it to AC volts and got 3 mV, so not an excessive amount of ripple. For the price it seems to be a fantastic deal.

I was delayed in continuing my electronics project, when I did resume I found that there was a fault in this new unit, which had passed beyond its return deadline. Even so the seller promptly upon understanding the issue sent a replacement power supply. This service was excellent, sometimes things get by and don't work & that's when you learn whether you are dealing with a reputable seller who is self-responsible, or not. This seller is excellent and stands 100% behind their product. This is significant today where you can buy a component or device and have no idea about who the manufacturer is or even if the product is real. Jesverty is a good manufacturer as indicated by the many positive reviews they receive - including this one!

My old power supply died so I found this one and it works great for anodizing titanium which is all I need it for. It’s easy to set up and use and everything is straightforward.

This power supply functions as specified. The voltage settings are difficult to set exactly and will drift slightly after setting. The current settings are difficult to set exactly and will drift slightly after setting.

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

Worked well for a couple of days measuring LiFe battery balancing, then suddenly blew a fuse. Then the spare fuse fractured when put into holder in power plug area then slid into place, see photo. Found more fuses locally and this power supply again blew the time delay T8A 250v fuse. Ordered the next better model for $10 more and will return this one. I see some other buyers had similar problems, so this is a design flaw, not a one-off failure. Gibing this one star

Product is great but seller is even better resolve an issue very quickly went out of their way they did not have to but very happy with the product that was sent.

Nice package, buttons and knobs feel solid, and displays are easy to read and interpret. Meets my needs well, and feels surprisingly well-built, though my experience with its higher-end competitors is limited (to much older equipment).

After a year I can tell that this product still working very good

Chegou bem rápido, bem embalado e o produto funciona perfeitamente.

A un paio di mesi dall'acquisto, con un uso non intensivo, mà frequente, nè sono pienamente soddisfatto; mantiene le promesse e la ventola parte solo sotto stress.

ファンの音が大きすぎる！しかも少ししか負荷を掛けていないので全開で回ります!!

Finition soignée, appareil conforme à la description, réglages cependant un peu délicats
