ISOMETER® IR155-3203/IR155-3204
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.

- Suitable for 12 V and 24 V systems
- Automatic device self test
- Continuous measurement of the insulation resistance 0…10 MΩ
– Response time for the first measurement of the system state (SST), < 2 s after switching the supply voltage on
– Response time < 20 s for insulation resistance measurement (DCP) - Automatic adaptation to the existing systemleakage capacitance (≤1 μF)
- Detection of earth faults and interruption of the earth connection
- Insulation monitoring of AC and DC insulation faults for unearthed systems (IT systems) 0…1000 V
- Undervoltage detection for voltages below 500 V (adjustable at factory by Bender)
- Short-circuit proof outputs for:
– Fault detection (high-side output)
– Measured value (PWM 5…95 %) and status (f = 10…50 Hz) at high or inverted low-side driver (MHS/MLS output) - Protective coating (SL 1301ECO-FLZ)
- Monitoring for unearthed DC drive systems (IT systems) in electric vehicles
