The ISOMETER? iso175 insulation monitoring device is designed for unearthed drive systems in hybrid, fuel cell, and electric vehicles.
The device reliably detects insulation faults, significantly contributing to both electrical safety and the availability of the electrical system. A key success factor is the use of an active, patented measurement method, which allows insulation monitoring even when the high-voltage system is de-energised, prior to the connection of the energy storage system.
Thanks to the integrated earth switch, no additional relays or contactors are required. The ISOMETER? iso175 also ensures reliable insulation measurements even with high system leakage capacitances of up to 10 μF. With its integrated CAN interface, the insulation monitoring device can be easily integrated into modern systems, providing additional information to support and simplify system analysis.

Long-Lasting Safety for E-Mobility in Public Transport
In modern electric buses, reliability, safety, and service life are critical. The ISOMETER? iso175 from Bender is specifically designed for use in electric commercial vehicles – and reliably supports your e-bus over a service life of more than one million kilometers. With a mean time between failures (MTBF) exceeding 139,000 hours in accordance with EN/IEC 61709, it continuously monitors high-voltage systems – even under demanding conditions such as continuous operation, vibration, and elevated temperatures.
The result: reliable insulation monitoring – for the entire lifetime of a city bus. *
* A typical city bus covers around 1,000,000 kilometers over its lifetime. At an average urban driving speed of 25 km/h, this translates to approximately 40,000 hours of operation – equivalent to about 12–15 years of daily service.
