AMF Control Relay
Function
Power House AMF relay: is a solid state, compact electronics device developed to make AMF panel reliable, simple, and easy to operate. It has built in Mains voltage Sensor, incoming delay timer, starting attempt timer with ON delay and OFF delay, 3 Attempt and lock, DG voltage sensors, counters, logic control etc. Incoming High Voltage supplies are isolated by opto-couplers and out put connections are through electrotechnical relays. The relay does not require any separate power supply. It works on DG set starting battery.
