Electricity meter | Alfa AS220 | Russia

A single-phase intelligent electricity meter of the Alpha SMART series with a modular design of direct inclusion of accuracy class 1.0 keeps records of active and reactive energy and power in single-phase AC circuits in single- or multi-tariff modes.

AS220 is used to build commercial accounting systems in:
Accounting systems (AIIS KUE) in the retail electricity market,
Smart Metering Systems,
Commercial and small-engine sector,
Private sector for household accounting.

FEATURES:
Load Limitation
Integrated power relay 100A
Hardware protection against changes in metrological characteristics of data
Measurement by module
Electricity quality control
Programmable threshold values of power grid parameters
Monitoring of electrical network parameters
The power relay integrated into the meter allows you to limit the power of the consumer's load, and it is also possible to configure the relay to turn off the load in case of an emergency increase in the mains voltage.

Communication modules
Thanks to the modular design of the meter, it is possible to install the following communication modules:

RS-485 interface
GSM/GPRS modem
GSM/GPRS modem with RS-485 interface (optional)

To remotely take readings from multifunctional electricity meters, Elster Metronica LLC offers modems of its own production – these are GSM/GPRS modems of the Metronica 100 series that withstand overvoltages in the 0.4 kV network.
