ISOMETER® IR155-4203/IR155-4204
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.

- Suitable for 12 V and 24 V systems
- Automatic device self test
- Continous measurement of insulation resistance 0…10 MΩ
– Response time < 2 s after power on for first estimated insulation resistance (SST)
– Response time < 20 s for measured insulation resistance (DCP) - Automatic adaptation to the existing system leakage capacitance (≤1 μF)
- Detection of ground faults and lost ground line
- Isolation monitoring of AC and DC insulation faults for unearthed systems (IT systems) 0 V…1000 V peak
- Low voltage detection for voltages below 500 V (value configurable EOL Bender)
- Short protected outputs for:
– Fault detection (high side output)
– Measurement value (PWM 5 % … 95 %) & status (f = 10 Hz…50 Hz) at high or inverted low side driver (MHS/MLS output) - Conformal coating (SL1301ECO-FLZ)
- Monitoring for unearthed DC drive systems (IT systems) in electric vehicles
