    Introduction

    The SDM630-MT is a multifunction meter that supports max 4 tariffs and 10 time segments, the tariffs and segments can be set via RS485 communication. The unit 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-MT 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 RS485 Modbus RTU outputs. Configuration is password protected.

    Unit Characteristics


    The Unit can measure and display:

    l Line voltage and THD% (total harmonic distortion) of all phases

    l Line Frequency

    l Currents, Current demands and current THD% of all phases

    l Power, maximum power demand and power factor

    l Active energy imported and exported

    l Reactive energy imported and exported


    The unit has password-protected set-up screens for:

    l Changing password

    l Supply system selection 1p2w, 3p3w,3p4w

    l Demand Interval Time(DIT)

    l Reset for demand measurements

    l Pulse output duration


    Two pulse output indicates real-time energy measurement. An RS485 output allows remote monitoring from another display or a computer.


    RS485 SerialModbus RTU

    This uses an RS485 serial port with Modbus RTU protocol to provide a means of remotely monitoring and controlling the Unit
    Set-up screens are provided for setting up the RS485 port.

    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.
