The meters are designed for unidirectional multi-tariff measurement of active and reactive electric energy and power, as well as electrical parameters in three-phase four-wired AC networks with subsequent accumulated data storage, generation of events and data transfer via optic port.

The meters are designed for indoor operation and can be installed in the areas with additional environmental protection (installed inside premises, cabinets or boards).

— Minimal overall dimensions in its class, DIN-rail mounting.

— Optical port for programming a tariff schedule and reading measured parameters and event logs.

— No magnet sensitive elements in measuring circuits and power supply system.

— All-in-one anti-tampering design, which breaks at attempt to be opened.

— The meter measures, stores, displaying on LCD and communicate information via different interfaces of active and reactive electrical energy independently by every tariff zone and cumulatively for all tariff zones for the following periods of time:

  • total cumulative energy;
  • energy at the beginning of the current day and 123 previous days;
  • energy at the beginning of the current month and 36 previous months;
  • energy at the beginning of the current year and the previous year;
  • consumption for the current day and the previous day;
  • consumption for the current month and 11 previous months.

— Energy measurement independently from current circuits phasing (measurement per module).

— TOU with the option of setting individual schedule for every day of the week based on 4 tariffs, 16 time zones per day. Individual tariffs
schedule is set every month. Minimal interval of each tariff during 24 hours is 1 minute.

— Measurement of electrical network parameters:

  • values of active, reactive and total power for each phase with the total power vector direction indication;
  • RMS of phase currents and voltages including those measured atone period of frequency for power quality analysis;
  • phase angles;
  • power frequency;
  • power factors of each phase and of their sum;
  • THD of sinusoidal phase lines.
— Recording of morning and evening peaks of active and reactive power at a specified interval from 1 to 60 minutes with a monthly
— Event logging including power quality events.
— Automatic self-diagnosis with error indication.
— Nonvolatile electronic crimped seal.
— Recording of unauthorized impacts in the indelible event log.
— LCD indication of data without main power.
