Eastron SEM3 is a new generation din rail mounted energy meter, equipped with RS485 connectivity. With multi-parameters measurement, SEM3 can be used for energy monitoring of various applications, such as PV energy management, smart building, industrial equipment, etc. The meter can be used as 1x 3phase energy meter or 3 individual single phase energy meter. In single phase mode, 3 external CT can be set with different CT ratio for three independent loads.

Eastron SEM3 measures and displays the characteristics of 1p2w, 3p4w, 3p3w supplies, including voltage, frequency, current, power and active and reactive energy, imported or exported, power factor, Max. demand etc. Energy is measured in terms of kWh, kVArh and kVAh. It provides 4 quadrant measurement.

Eastron SEM3 is designed in compact size with 1 modular width. To save installation and maintenance cost, all terminals of SEM3 adopt spring terminals or RJ terminals for easy connection. Warning is also available in case the phase sequence error happens.

Eastron SEM3 provides two measurement modes: Total mode and PV mode. In total mode, import and export energy will be measured separately. In PV mode, import and export energy will be balanced first, and the balanced value will be counted in import or export energy.
