KHTB Series

Compact isolated current sensing with a central busbar / cable aperture.

KHTB is a board-mount open-loop Hall-effect current transducer family for DC, AC, pulsed and mixed-current measurement. The primary conductor passes through the central aperture, while the secondary electronics remain galvanically isolated.
