Single Phase Smart Electricity Meter SL

The intelligent retro-style multi-tariff single phase electronic meter combines one or more communication interfaces and allows the utilities to receive the readings and other data about active and reactive energy, generation and consumption, voltage quality, tampering incidents, magnet exposure, etc. remotely. Available communication interfaces include G3-PLC, NERO-PLC, Radio (RF433 or RF868), LTE/GPRS, RS-485, and optical port.

Notifies the operator

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

Autonomous functioning

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

Phase/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.

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.

Load control relay

Allows you to remotely disconnect bad payers. Relay triggering is configured depending on profile and certain events.

Resistant to magnetic influence

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