Product Overview

The LEM DK-B420 B is a split-core DC current transducer designed for electronic measurement with galvanic separation between primary and secondary circuits. It features a 4-20 mA DC output current proportional to the measured current, offering DC bipolar measurement (magnitude and direction), three jumper-selectable ranges, and panel mounting. Key advantages include a large aperture, extended measuring range, high insulation, easy installation, and no insertion loss. Applications span renewable energies, power supplies, battery banks, and electric heating elements.
