Three-phase electronic electricity meter “AIST A300 H” is used for measuring and metering of active and reactive energy in three-phase AC circuits and transmission of telemetric information about consumed electricity when used in automated data acquisition systems. The meters are also divided by current and voltage.

The meter is additionally equipped with a data input-transfer unit (4G+Ethernet module).

Ethernet module allows to simplify remote reading and additional information from the meters. Ethernet modules work in any Ethernet network and are fully compatible with the global Internet.

4G module is an embedded module that allows data transmission from the meter to the server/hub through the network of cellular operators using 4G technology.
