    Introduction
    SDM630MCT-Mbus MID V.2 measures and displays the characteristics of single phase two wires (1p2w), three phase three wires(3p3w,) and three phase four wires(3p4w) supplies, including voltage, frequency, current, power ,active and reactive energy, imported or exported. Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured over preset periods of up to 60minutes. In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the product. The requisite current input(s) are obtained via current transformers(CT).

    This meter can be configured to work with a wide range of CTs, giving the unit a wide range of operation. Built-in interfaces provides pulse and Mbus outputs. Configuration is password protected.

    This unit can be powered from a separate auxiliary (AC or DC) supply. Alternatively it can be powered from the monitored supply, where appropriate.

     Unit Characteristics
    The Unit can measure and display:
    Line voltage and THD% (total harmonic distortion) of all phases
    Line Frequency
    Currents, Current demands and current THD% of all phases
    Power, maximum power demand and power factor
    Active energy imported and exported
    Reactive energy imported and exported

    The unit has password-protected set-up screens for:
    Changing password
    Supply system selection 1p2w, 3p3w,3p4w
    Demand Interval time
    Reset for demand measurements
    Pulse output duration 

    Two pulse output indicates real-time energy measurement. The Mbus output allows remote monitoring from another display or a computer.

    Current Transformer Primary Current
    The unit can be configured to operate with CT ratio between primary current and secondary current. The secondary CT has two options: 1A/5A

    MBus Output

    For MBus EN13757-3, the following MBus communication parameters can be configured from the Set-up menu:

    Baud rate 300, 600, 1200, 2400, 4800, 9600

    Parity none (default)/odd/even

    Stop bits 1 or 2
    Mbus network primary address nnn – 3-digit number, 001 to 250
    Mbus network secondary address 00 00 00 01 to 99 99 99 99 (The secondary address can not be set directly on meter, but can be done via Mbus communication)


    Pulse output
    This provides two pulse outputs that clock up measured active and reactive energy. The constant for active energy is 3200imp/kWh(Terminals 11&10). The pulse width for pulse 1 (Terminals 9&10) can be set from the set-up menu.
