The Sensata | Sendyne SIM100MOD is the first high voltage isolation monitoring / insulation monitoring / IMD device for Electric Vehicles (EV/HEVs) and charging stations capable of operating correctly even when the battery is active, and experiencing large voltage variations. The SIM100MOD continuously monitors the isolation resistance between a vehicle's IT (Isolated Terra) power system and chassis for deterioration of insulation and potentially dangerous levels of leakage current.
