Current transducer LEM LXS 6-NPS suitable for AC variable speed drives servo motors and UPS systems
Product Description
The LEM LXS series is a closed-loop, multi-range current transducer designed for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between the primary and secondary circuits. Key features include a voltage output, unipolar supply voltage, and a compact design for PCB mounting. Advantages include very low offset drift, excellent dv/dt immunity, LTS footprint compatibility, and an extended measuring range for unipolar measurement. Applications include AC variable speed and servo motor drives, static converters for DC motor drives, battery supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), power supplies for welding, and solar inverters. The product is intended for industrial application domains.
