ISOMETER® iso165C

ISOMETER® iso165C

  • 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 V…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.
