Automatic Start Generator Controllers

Automatic Mains Failure controllers (AMF) have all necessary functionality for generator control/monitoring and for Mains monitoring as well. So, this type of controllers combines features of generator controllers and ATS controllers as well. 

In case of Mains failure, AMF controller starts generator and switches load circuits from Mains to generator via external contactor pair or motorized changeover switch. When the mains voltage is recovered, the controller switches the load back to Grid and turn off a generator engine.  It also monitors genset engine sensors and stops generator in case of any critical alarm. 

Normally, this controller type is installed on the generator or near it.
