Product Overview
The LEM LES series are closed-loop, multi-range current transducers with voltage output and unipolar supply voltage. Designed for PCB mounting, they offer very low offset drift and excellent dv/dt immunity, making them ideal for electronic current measurement of DC, AC, and pulsed currents with galvanic separation. They are compatible with CAS footprint and suitable for industrial applications.
