The LEM LF 210-S is a closed-loop current transducer designed for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between the primary and secondary circuits, making it suitable for applications requiring high accuracy and very low offset drift over temperature. Its panel mounting design and robust features make it ideal for industrial environments.
