HLSR20-P/SP33 Description

Short technical summary and product information.

The LEM USA Inc. HLSR20-P/SP33 is an open-loop Hall effect current sensor from the HLSR series. It is designed for cost-effectiveness and features a compact, unique design occupying only 3.87 cm2 on the PCB with a height of 12 mm.

 

This sensor has a nominal current measurement of 20 ARMS and a measuring range up to 50 A. It provides high accuracy at 25°C (+/- 1% of Ipn) and at 105°C (+/- 3.4% of Ipn). The response time is a short 2.5 µs.

 

Operating within a temperature range of -40°C to +105°C, the HLSR20-P/SP33 utilizes a single +3.3 V supply. It features a voltage output of 0.8 V at Ipn and has fixed offset and gain. The through-hole PCB mounting model ensures reliable integration into designs.

 

Creepage and clearance distances are maintained at 8 mm + CTI 600, contributing to its suitability for various applications requiring robust current sensing.
