The meters are designed for multi-tariff measurement of active and reactive electric energy and power, as well as electrical parameters in two-wired AC networks with subsequent accumulated data storage, generation of events and data 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 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 independently by every tariff zone and cumulatively for all tariff zones for the following periods of time:
- total cumulative active and reactive energy;
- active energy at the beginning of the current day and 180 previous days;
- energy at the beginning of the current month and 48 (active) and 12 (reactive) previous months.
— 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.
— Measurement of electrical network parameters:
- instantaneous values of active, reactive and total power;
