DC power supply (0-120V,0-3A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supplies, output on/off/encoder knob

What a brilliant piece of kit it's a must have in your tool shed or garage I've powered and charged a couple of items 1 being a ebike battery once you set up the volts, ah, the rest is simple it monitored the charge the whole way through and kept it protected through out and the size of the unit itself is great I can just pop it on a shelf when not in use I actually charged my mobile phone from it at the same time and it was charging very fast if you're looking at these don't hesitate it's a good unit.

Great item works a treat great seller recommended

As an Electronics Engineer, I have accumulated a vast range of test equipment over the years. However, with new STEM Solar Energy Monitoring IoT boards, which I am designing, it is sometimes required to replicate a Solar Panel string, using a controlled variable DC supply in the lab. For this a ~40 to 120V DC power supply is required. Purchased this adjustable 0-120V DC Power Supply and upon its fast next day delivery, it has been pressed into service. Works very well. Output is accurate and easy to change voltage and current limits. More importantly, the power supply has a mains ON/OFF plus a DC Output On/OFF. So you can easily set the required voltage and just turn on the output when needed. This is a safety must for High Voltage DC supplies and good to see this on the PSU. Have checked the DC output on the scope, put on a Solar Invertor and also into a DC-DC SMPS and it works perfectly - clean enough for my lab testing. Would recommend, if you need a high voltage DC power supply for some projects. You just need to ensure you have the right voltage set BEFORE turning the DC output on! ** IMPORTANT. 75-120V DC is Dangerous and can cause Electric Shock and Muscular Inhibition! Please RESPECT this Power Supply Output and be careful!! **

It's cc/cv functions are perfect for monitoring lithium cells that I'm recovering. The high voltage means I can use it to bench test my hi voltage controllers. All round it is a very versatile piece of kit. 3 amps is a little low but it goes above 100 volts which would then make 3000watts at 3amps! I believe. so I wouldn't ask for more from it. Buy it 👍🏻 might buy another one with.lower voltage but higher amps for 12v equipment but it's perfect for my needs so far

Good power supply. Few noises. Pretty accurate calibration. Powerful. Suitable for my engineering solutions

I sent the first one of these back because it made so much audible noise when in current limit. It sounded like it was going to destroy itself. The second one was much better, but still makes some unnerving cracks and crackles when current limiting. I've used it plenty, so it does seem reliable enough. Cheap with a good user interface. The ability to check the voltage and current setting before enabling the output is a very good feature.

Compact and works well

I use it as a high tension supply for vintage valve radios. Quiet and no mains buzz. Ideal.
