Product Description

JBC-03 Microcomputer Relay Protection Calibrator

Darui Electric recommends for you

Detailed Description
The JBC-03 Microcomputer Relay Protection Calibrator can test various AC/DC currents, voltages, time, signals, reclosing, differential and other individual relays as well as complete relay protection panels. It can test the pickup voltage (current) value and release voltage (current) value of various relays, and the pickup time and release time of various contacts (normally open, normally closed, changeover, delay). Each test is automatically performed three times, the average of the three values is automatically calculated, and the test results can be printed.
Features
    Due to the use of microcomputer control, this instrument provides Chinese character prompts for operation. It also has a self-test and error reporting function. After power-on, the instrument immediately performs self-test, greatly facilitating inspection and maintenance. Such as "pickup voltage", "release voltage", "normally open pickup time", etc.
