    LEM LF 510-S High-Precision Closed-Loop Hall Effect Current Transducer

     

    LF 510-S Product Overview

    The LEM LF 510-S is a 500A rated current closed-loop Hall effect current transducer from LEM, the global leader in electrical measurement. Featuring patented ASIC technology, it delivers performance approaching that of fluxgate transducers at a Hall-effect price point.

    The transducer offers a ±800A measuring range (3x overload capability), <0.5µs response time, 200kHz high bandwidth, and ±0.6% full-temperature accuracy. Compared to the previous generation, total accuracy across the full temperature range has doubled, with maximum zero drift of only 0.1% IPN and a five-fold improvement in external magnetic field rejection.

    It supports a wide ±14.25V ~ ±25.2V power supply, outputs a 100mA current signal, and operates from -40℃ to +85℃, meeting EN 50155 OT4 requirements.
