LZSR Current Transducer Sensors

LEM LZSR Current Transducer Sensors are designed for precise measurement of DC, AC, and pulse currents, ranging from 80ARMS to 200ARMS, while ensuring galvanic isolation between primary and secondary circuits. These sensors offer outstanding performance with ultra-low offset drift as low as 3ppm/K, a significant improvement over previous generations that relied on traditional Hall-effect chips. Additional features include reference access, an overcurrent detection output, and operation on a +5V power supply, making the components highly efficient for various industrial applications.
