HLSR 32-PW-000

Current Sensors Overview

The HLSR 32-PW-000 is a board-mount current transducer from the LEM HLSR series, designed for accurate electronic measurement of DC, AC, and pulse currents. It utilizes open-loop Hall effect technology to provide galvanic isolation between primary and secondary circuits. The device features a nominal primary current rating of 32 A RMS, with a measuring range up to 2.5 times the nominal value. It operates on a single +5 V supply and delivers a voltage output. Key electrical specifications include a response time of 2.5 µs, an accuracy of 0.5%, and a bandwidth of 400 kHz. The unit supports through-hole mounting with a compact footprint.

Current Sensors Procurement Notes

Verify the specific suffix 'PW' against the manufacturer's official datasheet to confirm pinout configuration and output type variations within the HLSR series. Ensure the component meets required safety standards such as IEC 61010-1 and UL 508 for the intended industrial application environment. Cross-reference the part number with the latest product change notices to confirm availability and manufacturing status.

Current Sensors Selection Notes

Select this model when a 32 A RMS measurement range is required with high precision and fast response times. The HLSR series offers space-efficient integration suitable for PCB mounting. Consider the open-loop architecture for cost-sensitive applications where extreme linearity is not the primary constraint compared to closed-loop alternatives. Verify thermal management requirements based on the maximum operating temperature of +105 C.

Current Sensors Part Context

The HLSR series represents LEM's solution for compact, low-profile current sensing in industrial electronics. This specific model belongs to the HLSR-P variant family, which is optimized for through-hole mounting on printed circuit boards. The series is engineered to provide reliable performance in demanding environments, featuring factory calibration and a small footprint that facilitates dense board layouts.

Current Sensors Replacement Considerations

HLSR 32-P: Standard through-hole version without PW suffix variations. HLSR 40-P: Higher current rating variant within the same series. HLSR 16-P: Lower current rating variant within the same series.
