True RMS AC Current Transducer
DIN RAIL / PANEL MOUNT, TRUE RMS
The
CR4100
Series True RMS Current Transducers and
Transmitters are designed for applications where AC
current waveforms are not purely sinusoidal. More
precise and accurate than other transducers, these
devices are ideal in chopped wave and phase fired
control systems.
Applications
Phase fired controlled heaters
Quickly varying motor loads
Chopped wave form drivers
Harmonic currents
