Single Phase Relay Protection Tester with Microcomputer

Product Overview: The XHJB612 relay protection tester can test and verify the operating voltage/current values, return voltage/current values, operating time, and return time of various electromagnetic, rectifier, and transistor integrated circuit relays, as well as the operating values, return values, charging and discharging time, and operating time of reclosing relays. It can also test the starting current, sensing element operating current, instantaneous breaking element operating current, and operating time of GL and LL type inverse-time relays.

Performance Features
★ Large LCD screen with Chinese character display, easy to read and understand;
★ Real-time display of contact status, button-based switching of measurement ranges, simple and convenient on-site operation;
★ Passive output capability, flexibly used for auxiliary control during testing;
