Working Principle:
The power supply signal of the dual power supply controller and drive mechanism of this series depends on the A phase and N line of the input port of the common switch or standby switch. In the automatic state, when the incoming phase A and N common switch voltage is normal (AC190-240V), the public switch will be closed first regardless of whether the voltage of the public power supply B. C and the backup switch a.b.c and N is normal. At the same time, the power indicator and the public shutdown indicator light up. When the incoming public switch phase A and line N have no voltage, and th
