The LEM LAX SERIES is a closed-loop (compensated) current transducer utilizing Hall effect technology for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic isolation between the primary and secondary circuits, featuring a low-profile design for simplified integration with power modules. The transducer offers multirange capability with a single device and is suitable for industrial applications.
