The SEM1 Series is a new generation din rail mounted energy meter, equipped with Wi-Fi and RS485 connectivity. With multi parameters measurement, this energy meter can be used for energy monitoring of various applications, such as PV energy management, smart building, and industrial equipment.
It measures characteristics of 1P2W network, including voltage, frequency, current, power, active and reactive energy (imported or exported), power factor etc. Energy is measured in kWh and kVArh. Designed in a compact size, it utilizes spring terminals or RJ terminals for easy connection to save installation costs.
