Model# CTC AC Current Transducer/Transformer
Model# CTCR

Solid-Core RMS Current Transformer/Transducer

The CTCR series of transducers provides a non-contact, loop powered, method of current measurement. The dc output is directly proportional to the true RMS value of ac window current. Measurement ranges of 1A to 100A are available.
