Product Overview

The flexible Rogowski coil developed by Yuanxing Electronics provides a highly accurate and non-contact AC current measurement system. It supports a wide frequency bandwidth, extending from 10Hz – 1MHz, and can measure current from 0.1A to 300kA. These flexible rogowski coil current transformers also provide a high degree of linearity at 0.2%, an extremely low amplitude error of less than 1% at 25ºC, and 50 Hz, and give little sensitivity to position (±1%). The coils are made of flame retardant (UL94 V-0) and RoHS-compliant materials and operate between -20 ºC and 70ºC.
