The highly configurable Dilithium Design GFM (Ground Fault Monitor) is designed for use in a wide range of Electric Vehicle (EV) systems. The GFM measures the isolation between an electrical system ground and a separate High Voltage (HV) isolated system.
Features:
- Rapid and accurate isolation measurement
- Highly configurable
- Wide voltage range (30-500V)
- Fault location detection
- 2x programmable outputs
- 1x CAN Bus
- All measurements and information available over CAN bus
- CAN control of isolation measurement
- Factory calibrated
- Built in compatibility with:
- Dilthium Design MCU
- Dilthium Design EV Display
- Fellten CCS Controller
Applications:
- Automotive EV
- Marine EV
- Electric Vehicle Supply Equipment (EVSE)
- Hybrid Vehicles
- Energy Storage Systems
