Description

Features:

  • 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 (RF433 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 clipses, exceeding the energy and power limits;
  • Can be mounted on a DIN rail.


  • The meter measures and displays:
    • Network frequency;
    • Current in each phase;
    • Voltage in each phase;

    • Power factor in each phase.

    The meter controls:
    • Accounting 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 power integration in 1, 3, 5, 10, 15, 60 minutes;
    • Instantaneous power consumption;
    • Active energy consumption limits;
    • Low current consumption;
    • Supply voltage;
    • Consumed currents;
    • Network frequencies;
    • Phase sequence;
    • Phase loss.
