Product Description
Product Overview
The LEM LAH 25-NP is a closed-loop, multi-range current transducer utilizing Hall effect technology for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between the primary and secondary circuits, making it suitable for a wide range of industrial applications including AC variable speed drives, static converters, battery-supplied applications, UPS, SMPS, and welding power supplies. Key advantages include excellent accuracy, very good linearity, low temperature drift, optimized delay time, no insertion losses, high immunity to external interference, and current overload capability.
