An Automatic Mains Failure (AMF) panel manufacturing company builds control systems that automatically switch a power supply from the main utility grid to a standby generator when a power outage is detected. These panels constantly monitor the incoming power and, upon failure, automatically start the generator and transfer the load. When the main power returns, the AMF panel switches the load back and shuts down the generator. This ensures an uninterrupted power supply for critical systems in hospitals, data centers, and factories.
