ISOMETER® iso165C

ISOMETER® iso165C, iso165C-1

  • Insulation monitoring device (IMD) for unearthed DC drive systems (IT systems) in electric vehicles
  • Continuous measurement of the insulation resistance 0…50 MΩ, response values adjustable via CAN
  • AC and DC IT systems up to 0…600 V
  • CAN interface, 250 kBaud, internal terminating resistor 120 Ohm (iso1685C)
  • CAN interface, 500 kBaud, no internal terminating resistor. 2 additional High-Side drivers for fault message and response value (iso165C-1)
  • Power supply suitable for DC 9...16 V

The ISOMETER® monitors the insulation resistance between the active HV components of an electrical drive system (Un = DC 0…600 V) and the reference earth (chassis ground). The patented measurement technology is used to monitor the condition of the insulation on the DC side as well as on the AC motor side of the electrical drive system.
The ISOMETER® is assembled with three connectors. To achieve internal galvanic separation, connector 1 is connected to low-voltage (LV) areas and connectors 2 and 3 are connected to the HV areas in the car environment.
Due to its space saving design and optimized measurement technology, the device is
optimized for use in hybrid or fully electric vehicles. The device meets the increased
automotive requirements with regard to environmental conditions (e.g. temperatures and vibration, EMC). The ISOMETER® CAN bus interface allows it to integrate seamlessly into an existing CAN environment.

Caratteristiche

  • Insulation monitoring of AC and DC insulation faults for unearthed systems (IT systems) from 0…600 V peak
  • Power supply for all internal voltages
  • Continuous measurement of insulation resistance from 0 Ω…50 MΩ
  • Response time of ≤ 20 s for measured insulation resistance (using Direct Current Pulse (DCP))
  • Automatic adaptation to the existing system leakage capacitance (≤ 1 μF)
  • Detection of ground faults and lost ground line
  • Measurement of a second voltage
  • The device works when:
    – HV is unstable
    – HV is powered off
    – There are symmetric or asymmetric insulation faults
    – Faults exist between HV lines and the supply voltage
  • Galvanic insulation of all signals from the HV side
  • HV coupled network
  • CAN bus interface
  • Light weight: < 220 g (including housing and connection frame)
  • iso165C-1 only: The iso165C-1 variant features Error and Warning signals on the separated high-side driver
