Closed Loop Hall Effect Current Sensor HCB

5kV Isolation & <1μs Response for Critical Power Systems

Ultra-Precise Non-Invasive Sensing

The FERRTX Closed Loop Hall Current Sensor revolutionizes current monitoring with 0.1% linearity and DC-100kHz bandwidth, outperforming traditional DC Current Sensors in accuracy. Utilizing magnetic compensation technology, it achieves <1μs response time – 5× faster than Rogowski Current Sensors for overcurrent protection. With reinforced 5kV isolation and -40°C to +125°C operation, it replaces bulky lem split core current sensor solutions in space-critical designs.

Breakthrough Engineering

• Zero Insertion Loss
  Eliminates power dissipation vs. shunt-based AC Current Sensors

• Zero Magnetic Hysteresis
  Removes calibration drift inherent in hall split core current sensor

• CMOS/TTL Compatibility
  4.5-24V wide voltage range with ratiometric output

• EMC Immunity
  Withstands 200V/ns dv/dt noise in motor drives
