AMF Control Relay


Power House AMF relay: is a solid-state, compact electronics device developed to make AMF panels reliable, simple, and easy to operate. It has a built-in main 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.
