Manual Specifications Supplemental Document
The Yokogawa CW240 supports four single-phase two-wire systems, two single-phase three-wire systems and SCOTT connections. The CW240 supports currents ranging from 200.0 mA to 3000 A and voltages up to 1000 V. Electric power (instantaneous values, electric energy, and demand), harmonics, voltage fluctuations (dip, swell, and instantaneous power failure) and waveform scan all be measured simultaneously.
Yokogawa CW240 Features
  • Electric power analysis and power supply quality control in a single unit
  • Simultaneous measurement of loads in four systems(common to voltage)
  • Wide measurement range
  • Leakage current measurement in four channels
  • Wiring and Setting check function
  • A large amount of data can be saved
  • Analog input-output function
