Micro-computer Controlled Three-Phase Relay Protection Tester

Introduction:

GDJB-PC Relay protection Tester is applied to test the relay unit in relay protection system. At the same time GDJB-PC relay testers could be considered as a universal three phase AC/DC voltage source or current source. 

The test equipment can work alone or connected to computer, inside the relay controller there are new speed digital signal mini PC and real DAC (Digital-to-Analog Converter) template with new high fidelity and high power, the machine has large panel screen and rotating mouse. It is small in volume, high precision.
