The SIM200 Insulation Monitoring Device (IMD) is designed for continuous active monitoring of unearthed (Isolated Terra) DC systems including charging stations, electric vehicles, and any other system with a nominal operation above 60VDC.

The SIM200 is UL2231 recognized to ensure safety at the highest standards and responds to electric hazards quickly and reliably with a patented signal injection algorithm and processing for continuous “Always On” monitoring of insulation.

Additionally, this IMD provides robust self-diagnosis of its monitoring functions, modular CAN 2.0B interface for detailed system information, warning alarm with configurable level, fault alarm at 100Ω/V and configurable CAN ID for flexibility.
