Single Phase Smart Electricity Meter L

The intelligent multi-tariff single phase electronic meter is designed for use in smart electricity metering systems with remote collection of readings.  

The embedded IoT communication module allows utilities to receive information automatically about active and reactive energy, generation and consumption, voltage quality, tampering incidents, magnet exposure and etc. via radio (RF-433 or RF868) LPWAN, GSM or RS-485 technology.

Peculiarities
Resistant to magnetic fields

The counter withstands magnetic fields of 500 mlT, and also records the date and time of exposure.

Notify the dispatcher

The meter will promptly transmit to the dispatcher information about the facts of opening the terminal cover or case, exposure to a magnet, electrical disturbance, attempts to handle an incorrect password, deviation of network parameters, overheating, etc.

Load control relay

Allows you to remotely disable defaulters. Relay triggering is configured depending on certain events.

User's personal account

Electricity consumption and other indicators recorded by the meter can be monitored remotely in your personal account in any place where there is Internet.

Phase and zero current accounting

In addition to metering the current in the forward and reverse directions, the meter monitors and displays the network parameters, generation and consumption.

Autonomous functioning

In the event of a power outage, data will not be lost thanks to non-volatile memory. And the operation of the calendar and display is provided by a built-in battery with a long service life.
