Key Features

✅ Ultra-Low Voltage Detection
0-300V AC/DC residual voltage measurement with ±0.5% accuracy (IEC 61869-11 compliant) for rail power systems.

✅ Galvanic Isolation
5kV reinforced insulation withstands 25kV/m EMI interference (EN 50155/EN 50121-5 certified).

✅ Extreme Environment Operation
-40°C to +85°C wide temperature range with IP67-rated anti-corrosion housing for trackside deployment.

✅ Self-Diagnostic Intelligence
Real-time insulation degradation alerts and arc fault prediction via RS485/Modbus TCP interface.

✅ High-Speed Sampling
10kHz sampling rate captures transient residual voltages (<10μs pulse detection capability).

✅ Rail-Specific Safety
Fail-safe output circuits with SIL2 certification (EN 50129) for ATP/ETCS integration.
