CSPV-LAH: Precision Current Sensing Through Closed-Loop Hall Technology
The CSPV-LAH Closed Loop Hall Transducer sets a new benchmark in high-accuracy current measurement for industrial applications. Leveraging magnetoelectric effect sensing, this device measures DC, AC, pulse, and complex irregular waveforms with ≤0.1% linearity while maintaining electrical isolation – critical for safety and signal integrity.
Key Performance Advantages
Expanded Measurement Range: Handles 280A peak currents (100% overload) beyond rated 100A inputs
Ultra-Precise Output: 50mA ±0.5% signal output enables high-resolution monitoring
Environmental Resilience: Operates reliably in extreme conditions (-40°C to +85°C) with IP-rated vibration, dust, and humidity resistance
Broad Compatibility: ±12V~±15V dual power supply design
Technical Superiority Over Legacy Systems
The CSPV-LAH outperforms conventional solutions through:
Zero offset current limited to just 0.15mA (reducing calibration drift)
Sub-1μs response time with 200kHz frequency bandwidth
Seamless pin-to-pin replacement for VAC T60406-N4646-X400/8-X400 and LEM LAH 25-NP/LAH 50-NP sensors
Industry Impact
This transducer resolves critical pain points in EV battery management, industrial motor drives, and renewable energy inverters where traditional CTs struggle with DC offset and saturation. By maintaining ±0.5% output accuracy across temperature variations, it ensures system protection triggers operate within safety margins.
