WM3, IE38, IE14, WQ — electronic DIN rail energy meters
Country: Slovenia · Model: WM3 / IE38 / IE14 / WQ
Electronic DIN rail energy meters of the WM3, IE38, IE14 and WQ series, some with MID certification. The typical WM3x6 is a three-phase direct-connection meter with a base current of 5 A and a maximum of 65 A at 3×230/400 V. They are installed in LV boards, at EV charging stations and for sub-metering.

Description
WM3x6 is designed for 4-wire networks. The accuracy class for active energy is 1 per EN 62053-21 (class B per EN 50470-3) and for reactive energy 2 per EN 62053-23. The voltage 3×230/400 V has an operating range from −20 to +15 %, the frequency is 50 or 60 Hz, the voltage circuit consumes 8 VA per phase and the current circuit 0.8 VA. The meter measures active, reactive and apparent power and energy per phase and in total, voltages, currents, angles, frequency, power factor and the active tariff. The LCD has 7+1 digits with a resolution of 100 Wh, and the LED gives 1000 imp/kWh. The IR port is standard, RS-485 and M-bus are optional, and there is a pulse output per EN 62053-31 and a tariff input. The DIN rail housing per EN 60715 takes 3 modules, the terminal cover is sealable, and installation is indoors.
How to choose
The series is chosen by purpose. For charging stations WM3M4 or WM3M4C with MID, three- or single-phase, are used, and the V2 versions add cable loss compensation and OCMF 1.3.0 compliance. WM3M6 is three-phase with MID, IE38Mx are also three-phase, and IE14xx are single-phase, some with MID. WM1 is intended for reducing energy consumption and costs, and WQ shows instantaneous power, including under unbalanced load. For network analysis, see the MC7x0 instruments instead of a meter.
