The WMM & WMMC energy meters are intended for energy measurements in the three-phase and one phase electrical
charger stations.
The WMMC energy meter features high temperature operation and digital signing for a charging event, whereas WMM fea-
tures only high temperature operation. Both meters measure energy directly in 4-wire networks according to the principle of fast
sampling of voltage and current signals.
A built-in microprocessor calculates power, energy, current, voltage, power factor, power angle, frequency, harmonics of THD volt-
age and THD current harmonics. WMMC meter can detect and log events relevant for charging via RS communication. Thus
the meter can produce relevant digital signature for charging event.

The meters IE and IEM (MID certified) are intended for energy measurements in a single-phase electrical power network, and
can be used in residential, industrial and utility applications. Meters measure energy directly in 2-wire networks according to the
principle of fast sampling of voltage and current signals. They are equipped with a capacitive touch buton that allows the user to
scroll measurements and the menu, make setings,… and backlight for beter visibility. A built-in microprocessor calculates energy
and other electrical quantities from the measured signals. It also controls LCD, LED, IR communication, and optional extensions.
