SEM1-M-2

RS485 Din Rail Single Phase Energy Meter with CT Connection

  • Compact design
  • RS485 Modbus RTU
  • Easy connection solution
  • Bi-directional measurement
  • Multi-parameter measurements
  • Accuracy Class 1.0 active energy
Eastron SEM1-M-2 is a new generation din rail mounted energy meter, equipped with RS485 Modbus connectivity. With multi parameters measurement, SEM1-M-2 can be used for energy monitoring of various applications, such as solar PV system, smart building, industrial equipment, etc.
Eastron SEM1-M-2 measures characteristics of 1P2W network, including voltage, frequency, current, power and active and reactive energy, imported or exported, power factor etc. Energy is measured in terms of kWh and kVArh.
Eastron SEM1-M-2 is designed in compact size. To save installation and maintenance cost, all terminals of SEM1-M-2 adopt spring terminals or RJ terminals for easy connection.
The measurement mode of SEM1-M-2 is total mode. In total mode, import and export energy will be measured separately. Total energy equals to import energy plus export energy.
