Product Profile of SCR Power Controllers with Fault Signal Relay
SCR Power Controllers with Fault Signal Relay is offered with LED monitors for single phase, wrong sequence, under voltage, over voltage, start, inhibit, over current indication.
SCR Power Controllers can function in a current ranging from 12 Amps to 120 Amps.
SCR Power Controllers are fitted with 4 DIP switches to inhibit fault SPP, UV, OV and OC. SCR Power Controllers with Fault Signal Relay is offered in zero fired type design and can operate using different inputs of 0-10 V, 4-20 mA, 0-5 V, 1-5 V and 0-20 mA.
