LES, LESR, LKSR, LPSR, LXS, LXSR

Closed Loop Hall effect current sensors performing at the level of Fluxgate technology without the added cost.

LES, LESR, LKSR, LPSR, LXS, LXSR - Current Sensors

The LES, LESR, LKSR, LPSR, LXS, and LXSR families consist of current sensors meticulously crafted for the electronic measurement of DC, AC, and pulse small currents, ranging from 1.5 to 50 Arms nominal (including models at 6A, 15A, 25A, and 50A), with galvanic isolation.

These product lines boast features such as low offset drift and primary integrated conductors, ensuring reliable performance across a wide temperature range from -40°C to +105°C.

In addition, the LESR, LKSR, LPSR, and LXSR components offer reference access on an additional pin. Furthermore, both LPSR and LKSR parts feature a distinct primary footprint with 4 pins, enhancing creepage and clearance distances to 9.9 mm for superior insulation. The LPSR model includes an exclusive feature with overcurrent detection output.

It is worth noting that this product family seamlessly integrates with CAS, CASR, and CKSR sensors, as well as LTS and LTSR Series, ensuring compatibility and flexibility in various applications.

Primarily designed for industrial use, the LES, LESR, LKSR, LPSR, LXS, and LXSR series leverage closed loop hall effect technology, delivering performance akin to Fluxgate technology but without the associated added cost.
