220V ATS Dual Power Automatic Transfer Switch Cabinet

Under normal operating conditions, the load is powered by the main power source, while the control unit continuously monitors the status of both the main and standby power sources in real time. When the main power source suffers from power outage, abnormal voltage and other faults, the control unit captures the abnormal signals accurately. To avoid false switching caused by instantaneous grid fluctuations, the system sends a switching command after a short delay confirmation, and the automatic transfer switch seamlessly switches the load to the standby power source for continuous power supply. After the main power source is restored to normal, the control unit detects the normal power signal. With a preset delay buffer, the equipment automatically switches the load back to the main power supply, and the standby power source enters a hot standby state.
