DCL/DUCR Electronic DC Current Relay
Features
DC Overcurrent Relay for DC Motor
The milli-volt(mV) signals generated from the Shunt and power supply are sensed by solid state circuitry and compared with preset overload setting.
In case sensing overload condition, the internal relay switches contact after the preset delay. It has easier control operation. It has DC Overload and DC Underload protection relays.
It has wide DC current protection range from 1A to hundreds AMPS.
DC Ammeter maybe used instead of Shunt (DC Ammeter has its own shunt inside and keep 50mV maintained. )
