Insulation Monitoring Device
SIMD-10D2

The SIMD-10D2 is designed for real-time monitoring of insulation resistance in DC systems, including EV DC chargers, photovoltaic systems, and Battery Energy Storage Systems (BESS). It ensures safety and reliability by continuously monitoring the resistance between DC+ to PE and DC- to PE terminals.

Key Features

  • Dual channel design

    Supports two channel simultaneous monitoring. Lowers system wiring and complexity where two channels need to be monitored, such DC Fast Charger.

  • Voltage range

    Monitoring over wide input voltage range or 0 to 1000V DC.

  • User-Friendly Design

    A display and LEDs are provided for quick and easy status checks, simplifying tasks for production or service technicians.

  • Seamless Integration

    Easily integrate SIMD-10D2 into your equipment using the alarm relay.

  • Advanced Connectivity

    For more comprehensive interface needs, the device offers an RS485 Modbus RTU interface and an optional CAN interface.
