Product performance:
The transfer switch is an integration of two miniature circuit breakers with a motor and a mechanical rotation device, which detects the two power supplies through the controller, and, when there is anything abnormal existing in the circuit, the controller will form a logical judgment upon the detection result. Then the operating mechanism will be driven according to the controller command to turn on or turn down the switch, so as to ensure a safe and reliable power supply for the load.
