Excellent for the home hobbyist - easily manage the power volts and amps, going in to your project.
You will need probes, but this is great - and for the price, a real good deal

Product Description
Bench power supplies, also known as variable power supplies, are useful tools for testing and debugging circuits, as they allow you to adjust DC voltage on the fly. Some units can be configured to act as a constant current source, but in this video, Shawn shows you how to use a power supply as a constant voltage source with a configurable current limit.
Benchtop Power Supply
One of the most useful test bench tool for testing and debugging circuits especially in the event of a bad regulator or bad battery.
- under voltage lockout test
- LED test
- Project test

Make sure it dose not heat up or do what I said below at your risk. Works great though!
I really love this power supply. It has been working great since April-17-18 all the way to April-22-18. It is still working great. The only down side is that I had to rewire the fan to run all the time. The reason why is because the transformer inside of it was getting too hot. I had to solder a step down voltage circuit for the fan because I wanted it not to be on top speed all the time. The speed of the fan goes up when I turn the voltage up. That is how is supposed to work. I would recommend you to rewire the fan to work all the time or just get a step down voltage circuit and connect it to the supply circuit and then the fan. If you do not do that then the transformer will heat too much. You don’t want that because it can make the transformer go pop. Then say bye bye power supply. But anyways this power supply is great is great. Remember once you rewire that fan the item becomes no longer returnable. Rewire the fan at your own risk. If you short something out while doing that it will break it. Then you can no longer return it.Update: Has been working great since April-17-18. It has been working for about 14 months now and it quit working. I will be buying another one soon. I did not expect it to last very long because i used it a lot.Update: After about 1 year and a half it has stopped working. I was really loading it down so that’s why. If you don’t do the same like i did this thing will last for a while. It’s a great power supply i will be buying another one soon. Well it’s my fault for blowing it up but i will just get another one.
