Product code: 230 AR


The meters are designed for single-tariff measurement of active and reactive electric energy and power, as well as electrical parameters in three-phase three- and four-wired AC networks with subsequent accumulated data storage and transfer to the AMR/AMI system’s data collection centers.

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


The meter modifications are available with different rated voltage, rated and peak current, and additional functionalities which are not related to metrological perfomance.

— The meter measures, stores, displaying on LCD and communicate information via different interfaces of active and reactive electrical energy:

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

— Measurement of electrical network parameters:

  • instantaneous values of active, reactive and total power for each phase and for the sum of all phases with the total power vector direction indication;
  • RMS of phase currents and voltages;
  • phase angles;
  • power frequency;
  • power factors of each phase and of their sum.

— Multifunc tional pulse output including a load control function.

— Automatic self-diagnostics with error indication.
