ISOMETER® IR155-3203/IR155-3204

  • Insulation monitoring device (IMD) for unearthed DC drive systems (IT systems) in electric vehicles
  • Continuous measurement of the insulation resistance 0…10 MΩ, factory-set preconfigured response values
  • AC and DC IT systems up to 0…1000 V
  • Short-circuit protected driver outputs for fault detection and PWM coded Iso measuring value
  • Power supply suitable for 12 V and 24 V systems

The ISOMETER® iso-F1 IR155-3203/-3204 monitors the insulation resistance between the insulated and active HV-conductors of an electrical drive system (Un = DC 0 V…1000 V) and the reference earth (chassis ground > Kl.31). 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. Existing insulations faults will be signalised reliably even under high system interferences which can be caused by motor control processes, accelerating, energy recovering etc.
