Buy Three-phase electricity meter AIST A300 H LoRaWAN at JCOM IOT

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 (LoRaWAN module).

The LoRaWAN module allows to poll the meter and then send data to the server via LoRaWan wireless network. The radio frequency part of the device allows operation in the frequency range of 863-870 MHz.
