LES Current Transducers

LEM LES Current Transducers are designed for the precise electronic measurement of DC, AC, and small pulse currents, while maintaining galvanic isolation. These transducers are engineered for high accuracy, stability, reliability, and cost efficiency. The LES current transducers seamless integration with CAS sensors, providing enhanced compatibility and flexibility across various industrial applications. These transducers feature low offset drift and integrated primary conductors, ensuring optimal performance. Typical applications include AC variable speed and servo motor drives, static converters for DC motor drives, battery-supplied devices, and Uninterruptible Power Supplies (UPS).
