Features

  • Suitable for 12 V and 24 V DC systems (supply voltage)
  • Insulation monitoring of DC insulation faults for ungrounded systems (IT systems) DC 0…1000 V
  • Continuous insulation resistance measurement RF_corrected = 0…35 MΩ (RF_ original = 0…50 MΩ)
  • Response time ≤ 30 s for insulation resistances ≤ 500 Ω/Volt and system leakage capacitances ≤ 2μF
  • Insulation measurement for system leakage capacitances up to 10 μF can be configured by setting parameters in the high capacitance (“High Capacity“) profile.
  • Insulation measurement also when the vehicle's HV electric system is not energized
  • Integrated self-diagnosis (online self-test)
  • HV connection monitoring (offline self-test)
  • Continuous monitoring of the ground connection
  • Undervoltage detection
  • Ground connection can be disconnected
  • Interfaces:
    • Digital output for device error message (OKHS)
    • As an alternative
      • HS-CAN interface with the following protocols
        • Bender CAN
        • CAN-SAE J1939
    • All outputs short-circuit proof
  • Load-dump protection up to 58 V

  • High voltage disconnection function

Applications

  • Ungrounded drive systems in road vehicles
  • Onboard electrical battery isolation
  • Insulation Monitoring in aviation, ground-based and maritime EV applications
