HTA Family
Compact current sensors for AC and DC currents from 100 to 1000 ARMS nominal
HTA - Current sensors
The HTA current sensor family is purpose-built for the precise measurement of DC, AC, or pulsed currents while maintaining galvanic isolation between the primary and secondary circuits.
Current sensors of the HTA family operate efficiently with a bipolar power supply of +/- 15V. They provide an instantaneous voltage output of +/- 4V and offer a bandwidth reaching up to DC 50 KHz.
These sensors are designed with a round aperture for current measurement and are founded on open-loop Hall effect technology, rendering them particularly suitable for a wide array of industrial applications.
