Description

Current Transducer LKSR series

The LKSR series are closed-loop, multi-range current transducers with voltage output, designed for the electronic measurement of DC, AC, and pulsed currents. They offer galvanic separation between the primary and secondary circuits, featuring a unipolar supply voltage and a compact design for PCB mounting. These transducers provide very low offset drift, excellent dv/dt immunity, and are compatible with the CKSR footprint. They are suitable for applications such as AC variable speed and servo motor drives, static converters, battery-supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), power supplies for welding, and solar inverters. The series is certified according to various IEC and UL standards.
