SEM3-WL-2

Compact Size Three Phase Din Rail Wifi Energy Meter with 3 in 1 CT

  • Compact design
  • Wifi & RS485 Modbus
  • Easy connection solution
  • Bi-directional measurement
  • Multi-parameter measurements
  • Accuracy Class 1.0 active energy
  • Support 1x3p or 3x1p load measurements
  • Phase Sequence Automatic Detection
Eastron SEM3-WL-2 is a new generation din rail mounted energy meter, equipped with Wi-Fi and RS485 connectivity. With multi parameters measurement, SEM3-WL-2 can be used for energy monitoring of various applications, such as solar PV system, 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 CTs can be set with different CT ratio for three independent loads.
Eastron SEM3-WL-2 measures characteristics of 1P2W, 3P4W and 3P3W supplies, 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 SEM3-WL-2 has phase sequence automatic detection and alarm function. If the phase sequence is reversed, the meter will issue an alarm. The phase sequence can be adjusted through communication.
