Automatic Transfer Switch (ATS)
**Working Principle**
The controller continuously monitors the voltage and phase of the primary power supply. In the event of a power outage or abnormal supply, it drives the actuator to disconnect the main circuit and connect the backup circuit. When the mains power is restored, it automatically switches back to the original power supply line, ensuring that both power sources are never closed simultaneously.
**Application Areas**
1. **Electromechanical Power Distribution**: Automatic dual-power switching for data centers, base stations, and low-current engineering.
2. **Medical Facilities**: Uninterrupted emergency power supply for hospital emergency rooms and monitoring equipment.
3. **Commercial Buildings**: Backup power switching for high-rise buildings, shopping mall fire protection systems, and elevators.
4. **Finance & Security**: Continuous power supply for banks, surveillance systems, and access control systems during outages.
5. **Industrial Warehousing**: Prevention of production stoppages and losses in factory production lines and cold storage warehouses due to power failures.
