GDJB-PC3 Micro-Computer Controlled Three Phase Relay Protection Tester
Introduction:
* GDJB-PC3 Micro-Computer Controlled Three Phase Relay Protection Tester is applied to test the relay unit in relay protection system.
* At the same time GDJB-PC3 Micro-Computer Controlled Three Phase Relay Protection Tester could be considered as a universal three phase AC/DC voltage source or current source.
* GDJB-PC3 Micro-Computer Controlled Three Phase 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.
* GDJB-PC3 Micro-Computer Controlled Three Phase Relay Protection Tester is small in volume, high precision.
