CR4480 Average RMS AC Current Transducer - Three Element - 4~20mADC Output

The CR4480 Series Average RMS AC Current Transducers and Transmitters are designed to provide a calibrated DC output proportional to the AC current input. Designed for multi-point current sensing, these devices provide excellent features in a high value package. Average RMS is recommended when sensing current waveforms that have a fixed frequency, and are usually for loads operated from standard utility power.
