When the normal power is abnormal, the spare power works at once. When the normal power supply is normal, it will automatically switch back from the backup power to the normal power supply. We don't guarantee completely uninterrupted, but minimizing issues from power interruptions. This automatic transfer switch is suitable for the emergency power supply system with 50 or 60 Hz. Specially designed for household orbit-type installation and specially use in PZ30 power distribution box. The backup power supply is suitable for AC power. If the AC power supply through DC inverter is used, the voltage protector needs to be connected. 1.（Must be connected）Take zero line and fire line from the common control incoming line to connect AR (live wire) / AN (neutral line)
2.（Must be connected）Take zero line and fire line from the backup control incoming line to connect AR (live wire) / AN (neutral line)
3.The power indication signal is passive output, and the generator signal is taken (common) and (normally closed)
4.Connect the load end at the lower end of the (standby power supply side), Stepped wiring
5.There is an isolation board on the load. When wiring, first remove the isolation board, connect the load and then install the isolation board (it is recommended to connect the load first, then connect the backup power supply)
Note: The backup power must be connected to the city power AC230V, this is for PV type automatic transfer switch.
ATSE is composed of TSE and the controller. ATSE compiles with requirements of Low-voltage Switch Gear and Control Gear specified by GB/T14048. 11, Part 6-1 : Multiple functional equipment and transfer switch equipment.
