Product Description
1.GDJB-PC Microcomputer relay Protection tester is applied to test the relay unit in relay protection system.
2.At the same time GDJB-PC Universal Secondary Injection Relay Test Set could be considered as a universal three phase AC/DC voltage source or current source.
3.GDJB-PC Microcomputer relay Protection tester 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.

Main specification:
1.Intelligent mainframe that is used high speed DSP.
2.Separately running
