    LA25-P LEM Current Sensor | Closed-Loop Hall Effect Technology, Accurate Measurement You Can Trust


    LA25-P Precision and Efficiency for Reliable Current Measurement

    In industrial automation and power electronics, the accuracy and reliability of current measurement directly impact system performance and safety. The LA25-P current sensor, from the world-renowned LEM company, employs advanced closed-loop Hall effect technology to deliver a high-performance current detection solution for your equipment.


    LA25-P Outstanding Product Performance

    Designed for electronic measurement of DC, AC, and pulse currents, the LA25-P provides galvanic isolation between the primary and secondary circuits, effectively protecting downstream electronics and ensuring system safety. Thanks to its optimized design and high-quality materials, the sensor offers a linearity error of ±0.15% and an accuracy of ±0.91%, eliminating concerns about data deviation in any application. With low temperature drift, it maintains stable performance across a wide temperature range of -25°C to +85°C, reliably operating in various industrial environments. Additionally, its excellent immunity to external interference ensures accurate readings even in complex electromagnetic conditions.
