The EPQS meter is a multifunction device for measurement of electric energy in four-quadrants and is approved in accordance with IEC 62053-11, IEC 62053-22, IEC 62053-21, IEC 62053-23. Meter operates in 3- or 4-wire networks and can be direct connection (accuracy class 1) or CT or CT/VT connection (accuracy class 0.2s or 0.5s). EPQS meter can be easily incorporated into AMR systems. It has power quality monitoring capabilities and is designed to meet the most ultimate demands from utilities and other clients.

  • Measurement of active, reactive energy and maximum demand
  • Accuracy class: for active energy - 0.2s or 0.5s (connection via transformers), 1.0s (direct connection), for reactive energy - 2.0s
  • Up to 8 energy tariffs
  • Optical and electrical communication interfaces
  • Up to 8 programmable electrical pulse outputs (S0)
  • Load profiles and instantaneous values
  • Power quality monitoring
