Energy meter WM3x6

Energy meters WM3x6 and WM3M6 (MID certified) are intended for energy measurements in three-phase electrical power network and can be used in residential, industrial and utility applications.

Meter measures energy directly in 4-wire networks according to the principle of fast sampling of voltage and current signals. A built-in microprocessor measures active / reactive / apparent power and energy, current, voltage, frequency, power factor, power angle and frequency for each phase and total sum. 

The microprocessor also controls LCD, LED, IR communication and optional extensions.
