Automatic Mains Failure Panels



Automatic mains failure (AMF) panels – also referred to as automatic transfer switch (ATS) panels – make the power switch to emergency standby generators in the event of a significant loss of mains power or total blackout. Without AMF panels, generators need to be operated manually and that can mean lost data, potential damage to electrical equipment and huge amounts of disruption.

AMF board and ATS panels monitor the incoming AC mains supply, activate the standby generator when mains power fails and make an automatic electrical transfer of the building’s load from the mains to the generating set. When the mains supply returns, the ATS panel controls a return to the mains supply and shuts down the generator after a suitable cooling run. High-tech electronic control systems enable a wide range of activities, including full mains synchronization where a no-break changeover is required. LED indication lamps indicate supply availability and load switching status throughout, making the system truly independent.

The panel changeover device provides electrical and mechanical interlocking and meets IEC/BSEN 60947-6-1 requirements.

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.
