MODEL: LCY http://www.m-system.co.jp/ LCY SPECIFICATIONS ES-1993 Rev.6 Page 1/3 Power Transducer Series L-UNIT BIDIRECTIONAL CURRENT TRANSDUCER Functions & Features

  • Accepting 3-phase/3-wire AC current and voltage and detecting the magnitude and direction of the power flow by the phase angle of the signals
  • Providing standard DC signal in proportion to the AC current
  • DC output containing little ripple is ideal for computer input
  • Isolation up to 2000V AC
  • High-density mounting Typical Applications
  • Measuring AC current flow in a factory having private power plants (2.95) 112 (4.41) (2.95) mm (inch) MODEL: LCY–1[1][2]–[3][4]
