The WM3M4C energy meters areMID certifiedmeters, intended for energy measurements in thethree-phaseandsingle-phaseelectricalcharger stations.
The WM3M4C energy meter featureshigh-temperatureoperation anddigital signingfor a charging event.
WM3M4C energy meters measure energy directly andbidirectionalin 4 or 2-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 voltage, and THD current harmonics. WM3M4C meter candetect and log eventsrelevant for charging viaRS485communication. Thus the meter can produce relevantdigital signaturefor charging event.
