Thirdly, for defective batch products, we will investigate into the true problems happened, find the real reasons and discuss the suitable solution including recall them based on real situation.

13. What is difference between constant voltage (CV) and constant current (CC) power supply

A: Power supply is a device that provides electric energy for the load. The power circuit is what converts input electric energy into the desired form and outputs what called "power circuit". Power circuit can be roughly divided "constant voltage power supply" and "constant current power supply".

Constant voltage power supply is power circuit that controls output voltage at a constant level. It always provides a constant voltage regardless of the load and is widely used as power supply for electronic circuits.
