The WKO-2C series of closed-loop current transducers is designed for use in all industrial applications. It offers current measurement accuracy of better than 0.5% in the whole frequency range of dc to 120 kHz. The transducers use the most recent Hall effect elements, with an extended frequency response up to 120 kHz and an accurate phase response. The Hall effect sensor is integrated into the core instead of the air gap as with previous designs. Two cores are joined together, and the compensation effect of the two cores reduces interference from external magnetic fields. The units have an extended temperature range from -40 to 85 °C.
