GYID Insulation Monitoring Device for Electric Vehicle

GYID Insulation Monitor Features

For 0~1000VDC IT system.
Measurement of insulation resistance of 0~50MΩ
Monitor the insulation faults on the DC side, the AC side and the motor side;
Simultaneously monitor the positive and negative asymmetric insulation faults and symmetrical insulation faults;
Measuring battery pack voltage
Monitor the internal insulation faults of the battery pack and locate the fault point;
Monitor in the case of short circuit on the high-voltage DC side;
Reliably monitor insulation resistance in high-intensity interference, such as acceleration, deceleration, and energy recovery.
