The meters are designed for multi-tariff measurement of active electric energy and power, as well as measurement of electrical parameters in two-wire AC networks with subsequent accumulated data storage, generation of events and transmission of information 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, inside 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 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 month and 12 previousmonths.
— TOU with the option of setting a separate monthly schedule for weekdays, weekends and holidays based on 4 tariffs, 8 segments per day. Each month of the year is set for an individual TOU schedule.
— Measurement of instantaneous values of active power.
— Multifunctional galvanically isolated pulse output including control function.
— There are no magnet sensitive elements in measuring circuits and power supply system.
— Event logging.
— Small-size housing with DIN-rail mounting.
