Item		Specification	Remark
The number of input circuits		2
Input voltage		380V
Input mode		3-phase 4-line
Output signal of each AC input	1. For measuring	AC 1.5V, 3-phase common GND output (adjustable)	To the monitoring box of distribution unit
	2. For switching	AC 6.22V, 3-phase common GND output (Unadjustable)	To the automtic switch box

The AC voltage sampling board outputs two loops of AC sampling signals to monitoring box of distribution unit and AC automatic switchover box respectively. The monitoring box of AC and DC distribution unit- completes A/D conversion function, and sends the digital value to the PCU for display, at the same time judges if there is overvoltage/undervoltage alarm according to the digital value. Refer to 2.2.4.3 for its wiring. The signal output to the AC automatic switchover box will be compared with reference signal to complete automatic switching. Refer to section 2.5 for more information of AC automatic switchover box.
