AC Current Transducers
CR4220S Loop-Powered, Split Core, AC Current Transmitter - Single Element
0- 5 Amps
The CR4220S Series Average RMS 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.
