Introduction of AC panels
AC panels can be divided into 2 ways Automatic switch or Manual switch,it can also be 2 ways Automatic switch or Manual switch.和手切。
Switching configurations available AC contactor cut or dual power source device implementation.
The Feed out of the bus can be divided into Single busbar or Single busbar section.

4.1、Function of control and protection
(1)、Automatic controlling protection for over voltage；lower voltage and phase lack of two AC inputs.
(2)、Two ways Automatic switch or Manual switch.
4.2、Inspective function
(1)、Automatic inspection for three-phase AC voltage and current；
(2)、Busbar current measurement
4.3、Dispiay function
1、Display the three-phase AC of input module;
2、 Display the input of voltage;
3、Display the input of current;
4、Display three ways input of AC what put into operation instructions.
4.4、Alarm function
1、Alarm for lacked phase；
2、Alarm for loss of electricity.
