LEM HAS Panel Mount Current Transducers

LEM HAS Panel Mount Current Transducers provide a reliable solution for electronic measurement of DC, AC, and pulsed currents while ensuring galvanic isolation between the primary and secondary circuits. Utilizing open-loop Hall effect technology, the compact LEM HAS sensors support a wide measurement range from 50A to 600A, making these transducers suitable for various industrial applications. The HAS series features a voltage output proportional to the measured current, with excellent linearity and low offset drift over temperature. With an instantaneous voltage output of ±4V and a bipolar power supply requirement of ±15V, HAS sensors deliver accurate and efficient current sensing. Additionally, an extended bandwidth of up to 50kHz enables precise monitoring of fast-changing current signals.
