Active Current transformer Series WKO-2C-B
Double core technology closed-loop current transformers for railway engineering
Description
The current transducer WKO-2C-B with hall effect elements and double-core technology has an extended frequency response up to 150 kHz and an 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 ensures 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 mounting kit for busbars, molex connectors and feets for horizontal or vertical mounting.
