Power supply of E22

The power supply system is comprised of AC power supply sub-system and DC power supply sub-system.

²        AC power supply sub-system

Utilizing a power switch box, dividing the AC power consuming parts into two groups, and two groups are controlled by a main switch with a fuse. To avoid the problems of too high surge current, the system is equipped with time-delay switch, to make the groups are powered on in turn.
