HTFS – CURRENT SENSORS FOR LOW VOLTAGE APPLICATIONS
The HTFS current sensors, designed for low voltage applications, are utilized for the measurement of DC, AC, and pulse currents ranging from 200A to 800ARMS. These sensors provide galvanic isolation and are intended for PCB mounting.
The product family consists of 6 models, all featuring a uniform size with a 22 mm diameter aperture for the primary conductor.
They come with ratiometric offset, fixed gain, and reference access, and are designed to be panel-mounted onto PCBs with 4 holes of 3.5 mm diameter. Secondary connections are available for soldering on PCBs.
The HTFS current sensors rely on open-loop Hall effect technology, making them well-suited for various industrial applications.
