ISOMETER® IR155-4203/IR155-4204
- Insulation monitoring device (IMD) for unearthed DC drive systems (IT systems) in electric vehicles
- Continuous measurement of the insulation resistance 0…10 MΩ
- Insulation monitoring of AC and DC insulation faults for unearthed systems (IT systems) 0…1000 V
- Short-circuit proof outputs for fault detection and measured value
- Suitable for 12 V and 24 V systems
The ISOMETER® iso-F1 IR155-4203/-4204 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.
