An Automatic Mains Failure (AMF) panel manufacturer creates a crucial control system that automatically manages power supply transitions. The panel continuously monitors the main power source and, upon detecting a power outage or significant voltage drop, sends a signal to a standby generator to start. Once the generator is running and stable, the panel seamlessly transfers the electrical load. When the main power is restored, it switches the load back and safely shuts down the generator after a cool-down period, ensuring an uninterrupted power supply for critical operations.
