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 dropout voltage (current) value of various relays, and the pickup time and dropout time of various contacts (normally open, normally closed, changeover, time-delay). All tests are 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 machine provides Chinese character prompts for operation. It also has a self-test and error reporting function. After power-on, the machine immediately performs self-test, greatly facilitating inspection and maintenance. For example, "Pickup Voltage", "Dropout Voltage", "Normally Open Pickup Time", etc. Main Technical Parameters 1. AC voltage output: 0～250V continuously adjustable, maximum output capacity 1000VA 2. AC current output: 0～20A, 0～100A continuously adjustable At 0～20A, open circuit voltage 5V At 0～100A, open circuit voltage 10V 3. DC voltage output: 0～300V continuously adjustable, maximum 3A 4. DC current output: 0～200mA, 0～5A continuously adjustable At 0～200mA, open circuit voltage 48V At 0～5A, open circuit voltage 24V 5. Digital millisecond meter: Maximum range: 100 seconds Resolution: 0.001 seconds Accuracy: 0.01% ± 1 digit 6. Overall measurement accuracy: 0.5 class The JBC-03 Microcomputer Relay Protection Calibrator is a highly intelligent, multifunctional relay protection calibration instrument developed by our factory on the basis of the original.
