Manual Specifications Other1

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.


  • 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
