Active Current Transformer Series Wko-2c

Double core technology closed-loop current transformers

DESCRIPTION

REO has developed a new generation of closed-loop (C/L) current transducers which guarantees increased current measurement accuracy better than 0.3% in the whole frequency range: DC to 150 kHz.

The new current transducer type WKO-2C is a completely new development utilizing REO’s double-core technology magnetic design. The unit uses the latest Hall effect elements with an extended frequency response of up to 150 kHz and an accurate phase response.

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.

  • According to: EN 50178:1997, UL 94-V0
