HLSR Current Transducers

LEM HLSR Current Transducers are designed for accurate electronic measurement of DC, AC, and pulse currents while maintaining galvanic isolation between the primary and secondary circuits. These transducers feature low offset and gain drift, a short response time, and a voltage output. The HLSR series are available in two versions: HLSR-P for through-hole mounting and HLSR-SM for surface mounting. These transducers utilize open-loop Hall effect sensor technology for industrial applications that require dependable and precise current measurements.
