An Automatic Mains Failure Panel (AMF) , often abbreviated as AMF Panel, is an essential electrical control panel used in various applications to ensure the uninterrupted power supply to critical loads when there is a failure in the primary power source (mains power).  Commonly employed in settings where power continuity is crucial, such as data centers, hospitals, industrial facilities, and critical infrastructure.

The primary purpose of an AMF panel is to automatically switch the power source from the mains (utility power) to an alternative power source, typically a backup generator or an uninterruptible power supply (UPS), in the event of a mains power failure. This automated transition ensures that essential equipment and systems continue to operate seamlessly without any interruption.
