Product Description
Product Overview
The LEM LT 508-S6 is a closed-loop Hall effect current transducer designed for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between the primary and secondary circuits, offering excellent accuracy, very good linearity, low temperature drift, and optimized response time. This transducer is ideal for applications requiring high immunity to external interference and current overload capability, such as AC variable speed drives, static converters, UPS, and SMPS.
