we are offering amf 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. application:automation of dg sets. specifications:aux supply :12/24 v dc from dg starting batterysensingmains : 3 phase 4 wire.a) under voltage 170 -200 v. (adjustable)b) single phasingdg : 1 ph. 2 wire.a) starting signal withdrawal at 75 v. (fixed) b) load transfer 190 -210 (adjustable) mains incoming delay: 30 - 60 sec. (adjustable)starting signal a) on time 3-6 sec (adjustable) b) off time 3-6 sec. (adjustable) c) 3 attempt and lockideal running : 30-60 sec. (adjustable)stop solenoid timer: 30-60 sec. (adjustable)interlockin : logically interlockedisolation a) optical isolation for mains voltageb) optical isolation for dg voltagec) electro-mechnical relays for out putcontact ratings : 5 ampsterminals : pcb mounted for 2.5 sq mm wire.indications : a) mains incoming voltage (each phase) b) starting attempt on timec) set fail to startd) dg set low voltagee) load on dg f) load on mainsg) stop solenoid timer onenclosure : heavy duty sheet steel enclosure finishedwith powder coated.mounting : panel (245 x 190 mm)
