The SEM5-1 is the new generation of intelligent DIN rail mounted meters by Eastron. It integrates Wi-Fi & Lora communication. With multi parameters
measurement, SEM5-1 wireless energy meter 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 3x single phase energy meter.
Eastron SEM5-1 wireless energy meter measures the characteristics of 1P2W, 3P4W and 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.
Eastron SEM5-1 wireless energy meter is designed in compact size. To save installation and maintenance cost, all terminals of SEM5-1 wireless energy meter adopt spring terminals or RJ terminals for easy connection.
Eastron SEM5-1 wireless energy meter 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.
