Description:
The Eastron SEM3 is a next-generation DIN-rail mounted multifunction energy meter designed for precise monitoring of electrical systems in commercial, industrial, and renewable energy applications. Equipped with Wi-Fi (SEM3-WL) and RS485 Modbus RTU connectivity, the SEM3 delivers flexible integration into smart building systems, PV energy management platforms, and industrial automation networks. Its compact design supports both 1×3-phase and 3×1-phase measurement modes, allowing three independent single-phase loads with configurable CT ratios.
The SEM3 measures key electrical parameters—including voltage, current, frequency, active/reactive power, power factor, demand, and four-quadrant energy—and supports 1P2W, 3P3W, and 3P4W supply configurations. With features such as phase-sequence error warning, multi-parameter monitoring, and easy spring-terminal or RJ-terminal connections, the SEM3 ensures reliable, efficient, and user-friendly energy management for a wide range of installations.
