HTB Family

Measures from 50 A up to 400 ARMS for PCB mounting

HTB - Current sensors

The HTB current sensors facilitate the measurement of DC, AC, and pulsed currents within the range of 50 A to 400 ARMS nominal, ensuring galvanic separation between the primary and secondary circuits.

This sensor series comprises seven distinct models, all sharing a compact design to be mounted on a PCB within a mere 4.3 cm² area (with a height of 34 mm) and featuring a 16 mm diameter aperture. They provide voltage output and operate on a dual supply of +/- 12 to 15 V.

Specifically, the HTB-TP electronic components in this product series are equipped with a primary busbar.

The HTB current sensors employ open-loop Hall effect technology, making them well-suited for various industrial applications.
