DS Series Current Transducer

The DS series current transducers provide ultra-high accuracy, galvanically isolated AC and DC current measurement for demanding power electronics and energy applications. Based on closed-loop fluxgate technology, the DS series delivers excellent linearity, low offset drift, and wide bandwidth, making it well suited for precision power analysis, EV test benches, and laboratory or production test environments.

All DS models feature a compact mechanical design with a Ø27.6 mm aperture and current-output interface, enabling easy integration with precision power analyzers, data acquisition systems, and custom test setups.
