Image of LEM USA HTFS Series Current Sensors for Low-Voltage Applications The LEM USA HTFS series is engineered for precision current measurement in low-voltage environments, supporting DC, AC, and pulsed currents from 200 A to 800 A_RMS. Featuring galvanic isolation and a compact PCB-mountable design, each of the six models in the family maintains a consistent form factor with a 22 mm aperture for the primary conductor. These sensors incorporate ratiometric offset, fixed gain, and reference access and are panel-mounted via four 3.5 mm diameter holes, with secondary connections optimized for PCB soldering. Utilizing open-loop Hall effect technology, HTFS sensors deliver reliable performance across a wide range of industrial applications.
