Bench Power Supply Variable 0-30V 0-10A DC Power Supply Regulated CC/CV for Lab Teaching,DIY and Electronic Repair

Fantastic piece of kit - perfect for an electronics hobby

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 was surprised by the size of this power supply. Quite small and light. I found the instructions were simple to read, short but a little complicated concerning set up. Once understood this was straight forward. The brief explanation of constant current and constant voltage was a bit confusing. Having said that, once all set up, a very easy power supply to use. I checked the voltmeter against a tester and found it read slightly over but within acceptable tolerances ( within tolerances for my particular use +0.1v ) . Likewise amperage ( +0.1amp ). Fine tune and course tuning was easy to perform. I would recommend this item for workshop, hobby, amateur radio use and general purposes. Accurate enough for scientific or more accurate use….? Considering this is not, relatively speaking, an expensive power supply I consider it fit for purpose. If absolute accuracy ( if ever possible? ) is required then you would need to spend a considerable sum more in achieving this.Recommended.

Google skytoppower and the first result will be a uk.gov report on the dangers of using the model STP3005D-UK. High risk of shock.The report states amazon withdrew the product. I bought one from them some months after. There is no warning from amazon like a product recall etc. If you have one, you should return and I'd recommend not buying one or at least reading the report first if you haven't.Amazon are " investigating" and told me it should be withdrawn. So far it seems that means promoted adverts and banners for the product all over my front page.

decent machine

It does exactly what it was supposed to do, as described. It works well, it gives up to 35Volts out and delivered up to 10Amperes of current.

I had a slow bicycle charger for my bicycle battery, so I decided to use this DC unit.I set the 42.1 [V] and the maximum current the 4.02 [A] which means 169 [W] output power and I measured the input power was around 200 [W].For an hour this unit was delivering the DC power without any problem with minimal noise.After this test, I must say this is a very good quality device.

Update: The manufacturer has since sent a replacement unit, great service.I've had this since October 22, it's now Jan 23 and it's already not working properly and it's hardly been used. I can no longer get 60v out of it, the max that it will go is 30.5v with all the dials turned to max and tested with a multimeter too.
