LESR Current Transducers

LEM LESR Current Transducers are designed for high-precision electronic measurement of DC, AC, and small pulse currents, with galvanic isolation for enhanced safety and reliability. These transducers feature low offset drift and integrated primary conductors to ensure consistent performance. The LESR current transducers provide greater flexibility for system integration and seamlessly integrate with CASR sensors, ensuring compatibility across a broad range of industrial applications. These transducers deliver performance at a lower cost by leveraging closed-loop Hall effect technology. Typical applications include AC variable speed and servo motor drives, static converters for DC motor drives, battery-supplied devices, and Uninterruptible Power Supplies (UPS).
