±1% Accuracy with 5kV Isolation for Industrial Drives
The FERRTX HKC Series Closed Loop Hall Effect Current Sensor delivers laboratory-grade accuracy in harsh environments. Leveraging magnetic compensation technology, it achieves ±1% linearity across DC-10kHz bandwidth – outperforming traditional DC Current Sensors in dynamic response. With reinforced 5kV galvanic isolation and -40°C to +125°C operation, it replaces bulky lem split core current sensor solutions in space-constrained applications.
Zero Magnetic Hysteresis
Eliminates calibration drift vs. open-loop hall effect current sensors
Sub-μs Response Time
5× faster than Rogowski Current Sensors for overcurrent protection
Wide Voltage Compatibility
4.5-24V supply range (TTL/CMOS compatible)
EMC Immunity
Withstands 100V/ns dv/dt noise in VFD environments
▸ Bandwidth: DC–10kHz (captures motor drive transients)
▸ Accuracy: ±1% @25°C (±1.8% -40°C to +125°C)
▸ Isolation: 5kV RMS/60s (IEC 62368-1 certified)
▸ Response Time: <0.5μs
▸ Current Ranges: 50A, 100A, 200A, 500A
