PRC offers Microcontroller based programmable test equipment used to test all types of Auto Relay for Pull in  Dropout voltage This is offered in two modules

Control Module Relay Tester

This includes Microcontroller unit with LCDLED and Key pad for easy user interface to do the programming of Test Parameters

Power Supply Module for Relay

Output the various supply voltages as per input by control unit Monitoring terminals for Voltage and Current are provided on front panel

Mode of Operation

PRC Relay Test System has three modes of operations as below

Calibration Mode

Power supply output voltage is calibrated in this mode Calibrated at works

Test Mode

In this mode first Program mode is fetched After Programming the parameters LCDLED shows TEST MODE When TEST request switch is pressed supply voltage across the relay coil is increases till the relay is operated When relay is operated Pull in voltage is displayed on LCDLED Voltage increases till it reaches to maximum test voltage then voltage start decreasing till relay contact is dropped and drop out voltage is displayed on LCDLED
