The LA 55-P from LEM is a current transducer. It features instantaneous output, excellent accuracy, very good linearity, low temperature drift, optimized response time, wide frequency bandwidth, no insertion losses, high immunity to external interference and current overload capability. This current transducer is used for the electronic measurement of currents (DC, AC, pulsed, mixed) with galvanic separation between the primary circuit and the secondary circuit. It is mainly used in AC variable speed drives and 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.
