Here I am reviewing and showing basic usage of the Longwei and Kungber bench variable power supplies. Especially the difference between constant current and voltage and how to adjust them.
SAFETY POINT: I forgot to mention always disconnect the power supply from any load when turning it on and off, and when adjusting voltage and current!
