    The SDM630-Mbus V2 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 60 minutes. In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to power the product.
    SDM630-Mbus V2 supports max. 100A direct connection, saves the cost and avoid the trouble to connect external CTs, giving the unit a cost-effective and easy operation. Built-in interfaces provides pulse and Mbus outputs. Configuration is password protected.

     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(DIT)
    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.

    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 of pulse output 2 for active energy is 400imp/kWh (unconfigurable), its width is fixed at 100ms.
    The default constant of configurable pulse output 1 is 400imp/kWh, default pulse width is
    100ms.The configurable pulse output 1 can be set from the set-up menu.
