HV Adapter for Electric Vehicles

HVMeasuring Adapter

Electric vehicles (EVs) use high-voltage components that pose a safety risk to personnel. The HV adapter was developed to enable safe and reliable maintenance and safety-relevant tests on high-voltage systems.

We offer standard and custom adapter cable sets for easy mating and a low-resistance connection. Gold-sprung test probes ensure a quality connection without degrading the mating surface.

The HV adapter can be used to:

• Determine if an HV system is voltage-free
• Measure the voltage in an activated HV system
• Check or measure the insulation resistance in an HV system
• Simulate insulation faults in an HV system
• Check or measure the HV interlock or pilot line in an HV system
• Open or bridge the HV interlock or pilot line
• The HV adapter is a valuable tool for EV maintenance and safety
