HAX Series

Compact current sensors for AC and DC currents from 500 to 2500A

HAX - Current Sensors

The HAX current sensor family enables electronic measurements of DC, AC, or pulsed currents while ensuring galvanic isolation between the primary and secondary circuits. 

These sensors provide an instantaneous voltage output ranging of +/-4 V, operate using a bipolar power supply of +/- 15 V, and offer a DC bandwidth of 25 KHz.

HAX current sensors are designed based on Hall effect open-loop technology and are specifically tailored for use in industrial applications.
