SIM200 Module
绝缘监测设备
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.
Software and setup file downloads are available below. For CAN protocol documentation and other resources, please contact Sensata.
