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.
  • CAN bus communication
