WM3M4 & WM3M4C Three-phase electrical energy meters for charging stations User 's Manual
▲Description of the device
■Functionality of WM3M4 & WM3M4C
●The WM3M4 & WM3M4C energy meters are MID certified meters, intended for energy measurements in the three-phase and single-phase electrical charger stations. The WM3M4C energy meter features high temperature operation and digital signing for a charging event, whereas WM3M4 features 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 voltage and THD current harmonics. WM3M4C meter can detect and log events relevant for charging via RS485 communication. Thus the meter can produce relevant digital signature for charging event.
