3-Phase Voltage Transducer
The CR473 series Voltage Transducers are expanded scale instruments designed to accurately measure three-phase voltages

The CR473 series Voltage Transducers are expanded scale instruments designed to accurately measure three-phase voltages. Each model produces three discrete 4-20 mA signals which are proportional (across the selected input voltage range) to the three-phase input voltage. The output is a true constant current driver which is unaffected by resistance variations in the output loop of 0-600 ohms. The CR4730 is designed to measure line-to-line voltages and the CR4731 to measure line-to-neutral. Both are average-reading, calibrated to read RMS. Features include:

  • Permanently calibrated
  • Fully isolated
  • ANSI/ISO 50.1 Class L3
