ACTIVE CURRENT TRANSFORMER SERIES WKO-2C-B

Double core technology closed-loop current transformers for railway engineering

The current transducer WKO-2C-B with hall effect elements and double-core technology has an extended frequency response up to 150 kHz and accurate phase response. The WKO-2C-B guarantees an increased current measurement accuracy better than 0.3% in the whole frequency range: DC to 150 kHz.

A completely redesigned electronics ensure that the new C/L current transducer has better drift compensation and an extended temperature range from -40°C to 85°C.

Modular design

The current transformer has a modular design which allows a variety of mounting options. The cost-effective basic model consists of a housing with screw terminals, bushing for cable and holes for fixing. Optionally, the transducers are available with a mounting kit for busbars, Molex connectors and feet for horizontal or vertical mounting.
