LEM 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.

The HLSR sensors provide access to a voltage reference and offer space-efficient integration with a compact footprint of 3.87cm² x 12mm. These sensors are available in five measurement ranges: 10ARMS, 20ARMS, 32ARMS, 40ARMS, and 50ARMS, with a measuring range up to 2.5 times the nominal primary current. These measurement ranges ensure high precision and reliability across various industrial applications that demand stable and accurate current sensing. Typical applications include AC variable speed drives and servo motor drives, static converters for DC motor drives, battery-supplied applications, UPS, and Switched Mode Power Supplies (SMPS).
