LEM HC16F 1400-S00 HC16F Automotive Current Transducer

1400A Rated Current x ±1400A Measuring Range — High-Performance Open-Loop Sensor for Automotive Motor Control

LEM HC16F 1400-S00 Product Overview

The HC16F 1400-S00 is an open-loop Hall effect current transducer from LEM's HC16F series, designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits. This through-hole version is specifically engineered for high-power automotive applications, featuring a dual ASIC configuration that effectively cancels external magnetic fields and provides excellent cross-talk immunity. The sensor's dual air-gap design significantly reduces core size and weight compared to conventional C-core sensors, with a footprint of only 37.2 x 32.6 mm and a mass of 29 g.

Rated for 1400 A nominal with a ±1400 A measuring range, it outputs a fully ratiometric voltage of 2.5 V ± 2 V (instantaneous) with ±1.75% accuracy and ±0.5% linearity. Sensitivity is 1.43 mV/A. Response time is 4 µs and bandwidth is 40 kHz. Supply voltage is +5 V (4.85 to 5.15 V) with a maximum supply current of 35 mA. Operating temperature is -40°C to +125°C.

LEM HC16F 1400-S00 Key Advantages

The HC16F 1400-S00 employs open-loop Hall effect technology with a proprietary dual ASIC, delivering ±1.75% accuracy and ±0.5% linearity while maintaining very low thermal offset and sensitivity drift across the entire -40°C to +125°C temperature range. The ±1400 A range provides ample headroom for transient overcurrent conditions, while the 4 µs response time and 40 kHz bandwidth capture fast-changing motor drive and switching waveforms with high fidelity. The PCB through-hole design enables robust mechanical mounting and easy integration onto gate driver boards, and the circular aperture accommodates both rectangular and round busbars. The integrated sleeve provides high-voltage isolation, and the unipolar +5 V supply simplifies power design. The dual ASIC architecture effectively eliminates external magnetic field interference, ensuring robust performance in electrically noisy automotive environments.
