Rectifier Protection Relay Unit is used for the protection of the high current rectifiers monitoring the output current and when the current will exceed the preset value a relay will be de-energized. The Relay Unit works on an input power supply of 230V with a frequency of 50Hz and comes with ten turn helical potentiometer with counter for setting the trip current reset switch for resetting the relay. The Relay Unit is de-energised after detecting the overload and will remain in that state until the reset switch is pressed. Rectifier Protection Relay Unit is designed to accept 50mV full scale shunt output and trip current can be set using this potentiometer.
