Bench Power Supply Variable 0-30V 0-5A DC Power Supply Regulated CC/CV for Lab Teaching,DIY and Electronic Repair STP3005D EN61010-1

Wanted to have a variable power supply forages and after some research I plummed for this one. Wasn't disappointed. Lovely looking until but functions as expected. Easy to set up with supplied cable and seems very stable over time (as checked on my Fluke multimeter). Can be used on a wide variety of projects and I've used it with Ardunio without problems. It's also very silent in operation and at lower voltages/currents the fan hardly comes on at all. The unit has a very small footprint so would fit anywhere in your lab/hobby room. I would highly recommend this unit but the only downside as far as I can see is that the instructions haven't been translated as well as they could have been.

I've has considerable success using this PSU for hobby and pro use over the last year.I made an external on/off switch for the output, since you can't tell if it's set to too-high a voltage until it's turned on.The gripe which has been annoying me more and more, though, is that the display is dim. OK indoors, but when I move it into my lockdown lab in the conservatory the display is hard to read even when I shade it.There doesn't seem to be any brightness adjustment, even if you take the case apart.

You do the research and then place an order - hoping to get the best product.Well this is definitely an excellent product and with good customer support. I contacted the seller with a question that they answered almost immediately and the power supply is performing as I expected, charging 18650 cells in a safe manner. The ability to have accurate and variable voltage selection is great as most power supplies are fixed voltages.I cant say more about the company and the product - it's perfect...

Very good price very easy to set up and use. The display is clear and bright. Great to have constant current and constant voltage settings nice and slim unit. Best power unit I’ve got

I have to say I was sceptical of a power supply at this price point.It arrived promptly and obviously my first port of call was checking the output with a few multimeters.I needed have worried not only was it within 99% but there is a feature to adjust the reading to the output allowing you to correct any discrepancy.Better built than anticipated and so far with a few weeks use has been ok.

Compact ,accurate and easy to useAt this great price what more could you wantTruly a pleasure to use

Very good for the price; accurate at 10mV

Dead on arrival. No output voltage. Useless.Very disappointed.
