The Delta reverse power relay is used in conjunction with load sensing circuits, e.g. Woodward 2301 load sensor, Barber Colman ILS, Crompton Parkinson or similar watt meter transducer.
Under reverse power conditions the output signal from the load sensing device reverses. The Delta Reverse Power Relay monitors this signal and operates at a preset reverse power level. The output relay has two sets of changeover contacts which electrically latch when operated.
The relay is reset by disconnecting the input supply.
