The Sendyne SIM100MLP is the first high voltage isolation monitoring device. Sendyne SIM100MLP for EV/HEVs capable of operating correctly even when the battery is active, and experiencing large voltage variations, no variations, or even if the battery is not connected. The SIM100MLP continuously monitors the isolation resistance between a vehicle’s Isolated Terra power system and chassis for deterioration of isolation and potentially dangerous levels of leakage current. The module detects not only resistive leakages but also capacitively stored energy that could be harmful to human operators.
Due to a proprietary, patented and patent pending advanced algorithm, the module is capable of detecting all sources of leakage including multiple, simultaneous symmetrical and asymmetrical faults, as well as resistive paths between the chassis and points in the battery with the same potential as the chassis. The Sendyne SIM100MLP was designed as a component for systems complying with ISO 6469-3:2011-12, UL 2231-1, UL2231-2, IEC 61557-A, CFR 571.305 and other applicable standards.
