Product introduction:
The QBMC-3 insulation monitor uses DC injection method to measure the insulation of the crane, etc. The test voltage is DC24V. If the corresponding line in the equipment is enabled, the instrument and the circuit contactor or circuit breaker auxiliary contact are interlocked and controlled to realize the isolation of the insulation monitor from the power grid when the motor circuit is powered on. When the line is powered off, the insulation monitor automatically starts to monitor the insulation of the line. This instrument can measure three different devices to be measured
