Product Overview
The LAH 100-P is a closed-loop (compensated) 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. Key advantages include excellent accuracy, very good linearity, low temperature drift, optimized delay time, wide frequency bandwidth, no insertion losses, high immunity to external interference, and current overload capability. This transducer is designed for industrial applications such as AC variable speed drives, servo motor drives, static converters for DC motor drives, battery supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), and power supplies for welding applications.
