EW800Distributed multifunction meter

Our distributed meter is designed to accurately measure energy consumption of systems and machines. Based on the IoT, it collects data in real time and automatically send them to the Data Manager for analysis. Hence, it promotes energy efficiency and digitalization in the plant.

  • Graphic Display 256×96 pixels, with white LED backlighting.
  • Intuitive menus with resistive touch screen interface.
  • Data transmission to the Data Manager through RS485 ModBus or Radio Sub1Ghz (868MHz).
  • Possibility to connect up to 250 devices to a single EW900 Data Manager.
  • Single or three-phase energy meter.
  • Measurement of active, reactive and apparent energy
  • Measurement of active, reactive and apparent power
  • Electrical parameters measured: current, voltage, active, reactive and apparent power, power factor
  • Line quality: harmonics (1st…51th), THD.
  • Precision: class active energy.
  • Data refresh on display: 1 second.
