Product Description
Product Overview
The LEM LA 130-P is a closed-loop Hall effect current transducer designed for electronic measurement of DC, AC, and pulsed currents with galvanic separation between primary and secondary circuits. It offers excellent accuracy, very good linearity, low temperature drift, and optimized response time, making it suitable for various industrial applications such as AC and DC motor drives, UPS, SMPS, and welding power supplies. The transducer features an insulating plastic case recognized according to UL 94-V0 and provides high immunity to external interference with current overload capability.
