ISO175-32-SB Insulation monitoring device

The ISOMETER iso175 product line is an insulation monitoring device for unearthed drive systems in hybrid and electric vehicles.

Features

- Patented, active measuring method

- Insulation measurement, even if the vehicle's HV on-board system is not live

- Detection of symmetrical and asymmetrical faults

- CAN bus interface

- Automatic adaptation to the leakage capacitance of the system (up to 10 µF depending on the profile)

- Integrated self-diagnosis (online self-test)

- HV connection monitoring (offline self-test)

- Continuous monitoring of the earth connection

- Function for switching off the high voltage

Technical features

- Suitable for 12 V and 24 V DC systems (supply voltage)

- Insulation monitoring of DC insulation faults for unearthed systems (IT systems) DC 0...1000 V

- Continuous measurement of the insulation resistance RF_corrected = 0...35 MO (RF_original = 0...50 MO)

- Response time = 30 s for insulation resistance = 500 O/volt and system leakage capacitance = 2µF

- Insulation measurement for system leakage capacitance up to 10µF possible through parameterization (Profile High Capacity)

- Insulation measurement even when the HV vehicle electrical system is de-energized

- Integrated self-diagnosis (online self-test)

- HV connection monitoring (offline self-test)

- Continuous monitoring of the earth connection

- Undervoltage detection

- Disconnectable earth connection
