Dual-supply automatic transfer switches are now accepted by more and more customers. Each customer needs different functions and different needs and functions. Next, we will talk about common dual-power automatic conversion. Switch several functions.

1. Self-returning self-recovery: When the common power supply is normal, the controller issues a command, the common power supply control circuit breaker is combined, the standby power supply control circuit breaker is divided, and the dual power supply automatic transfer switch electrical device is in the (1, 0) state. When the common power supply is abnormal, the controller issues a command, the common power supply control circuit breaker is divided, the standby power supply control circuit breaker is closed, and the dual power automatic transfer switch electrical device is in the (0, 1) state. When the common power supply returns to normal, the controller issues a command, the common power control circuit breaker is combined, the standby power supply control circuit breaker is divided, and the dual power automatic transfer switch electrical device is in the (1, 0) state.

2, self-return is not self-recovery: When the common power supply is normal, the controller issues a command, the common power supply control circuit breaker is combined, the standby power supply control circuit breaker is divided, and the dual power automatic transfer switch electrical device is in the (1, 0) state. When the common power supply is abnormal, the controller issues a command, the common power supply control circuit breaker is divided, the standby power supply control circuit breaker is closed, and the dual power automatic transfer switch electrical power supply is in the (0, 1) state. When the common power supply returns to normal, the dual power automatic transfer switch appliance is still in the (0, 1) state. Only the operation of the "reset" button can make the common power control circuit breaker, the standby power control circuit breaker, and the dual power automatic transfer switch. The appliance is turned back to the (1,0) state.

3. Mutual standby: When the common power supply is normal, the controller issues a command, the common power control circuit breaker is combined, the standby power supply control circuit breaker is divided, and the dual power automatic transfer switch electrical appliance is in the (1, 0) state. When the common power supply returns to normal, the dual power automatic transfer switch appliance is still in the (0,1) state, and only the standby power supply is cut off, so that the common power supply control circuit breaker can be combined, the standby power supply control circuit breaker is divided, and the dual power supply automatic transfer switch electrical appliance Only then turned back to the (1.0) state.
