Description

Features of three phase smart meter:

  • Active energy accuracy class 0.5S / 1; for reactive energy: 0.5 / 1;
  • Simultaneous collection of data via PLC and radio interfaces;
  • Communication interfaces: Radio (RF434 or RF868), GSM / LTE, RS-485, PLC, G3-PLC;
  • Removable GSM/LTE modem or DATD;
  • Records the mains frequency, current and voltage in each phase, angles between the vectors of phase voltages and vectors of phase currents of voltages, power factor in each phase;
  • Signals about tampering with the housing cover and the terminal block clips, exceeding the energy and power limits;
  • Can be mounted on a DIN-rail.


  • The three phase smart energy meter measures and displays:
    • Mains frequency;
    • Current in each phase;
    • Voltage in each phase;
    • Angle between current and voltage in each phase;
    • Angle between phase voltages;
    • Power factor in each phase.

    The meter controls:
    • Records for four energy profiles: active and reactive, forward and reverse directions with an interval of power integration of 1, 3, 5, 10, 15, 60 minutes;
    • Consumed active power direction with an interval for power integration in 1, 3, 5, 10, 15, 60 minutes;
    • Instantaneous power consumption;
    • Limits for active energy consumption;
    • Low current consumption;
    • Voltage supply;
    • Consumed currents;
    • Network frequencies;
    • Sequence of phases;
    • Phase loss.
