Mains Failure Panel
Auto Main Failure Panels, also known as AMF panels, are used to automatically changeover from mains electricity supply
to stand-by generator or gen set on failure of the mains supply. When the mains supply is restored, the system
automatically changes back and stops the gen set. The stand-by generator will be eventually shut down after a short cooling down period.
We manufacture and supply AMF (Auto Mains Failure) Panel as per the specific requirements of the clients.
These panels are used for controlling power supply in various industries like processing plants, hospitals etc.
On the request of the clients,we customized these panels (both automatic and manual modes) to meet client-specific requirements.
