True RMS AC Voltage Transducer
DIN RAIL / PANEL MOUNT, TRUE RMS
The CR4500 Series, True RMS Voltage Transducers and
Transmitters are designed for applications where AC voltage
waveforms are not purely sinusoidal. More precise and
accurate than other devices, these units are ideal in chopped
wave and phase fired control systems.
Applications
Phase fired controlled devices
Quickly varying voltage supplies
Chopped waveform drivers
Harmonic voltages
Features
35mm DIN rail mount or panel mount
Available with 0-5 VDC, 0-10VDC or 4-20 mADC output
24 VDC powered
Highest precision available
Outputs isolated from inputs
