The CW Series Current Transducer is designed to convert an input current signal into a proportional output voltage. It is capable of accurately measuring sinusoidal AC current (up to 25 kHz), DC current, and pulsating DC current. The transducer provides an output voltage that is linearly proportional to the measured current, with galvanic isolation between the input, output, and auxiliary supply, ensuring safe and interference-free signal transmission.
