Product Description
Product Overview
The LEM LT 208-S7/SP1 is an insulated current sensor designed for measuring DC, AC, and pulse currents. It utilizes Hall effect technology in a closed-loop (compensated) system, offering excellent accuracy, linearity, low temperature drift, and fast response times. Its design features an insulated housing compliant with UL 94-V0 standards, providing strong interference immunity and current overload capability. This sensor is suitable for various industrial applications including variable speed drives, DC motor traction, battery power, UPS, SMPS, and welding power supplies.
