ISOMETER® IR155-4210

ISOMETER® IR155-4210

  • Insulation monitoring device (IMD) for unearthed DC charging systems (IT systems) for DC charging stations according CCS standard
  • Continuous measurement of the insulation resistance 0…10 MΩ, factory-set preconfigured response values
  • IT systems up to 0…800 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® IR155-4210 monitors the insulation resistance between the insulated and active HV-conductors of an DC charging station according CCS standard (Un = DC 0…800 V) and PE. 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/charger system. Existing insulations faults will be signalised reliably even under high system interferences which can be caused by motor/charger control processes, etc.
