    SDM630MCT-2T MID V.2 is a three phase multifunction DIN rail meter. It can measure and display the characteristics of 1p2w,3p3w and 3p4w supplies, including voltage, current, power, active and reactive energy imported or exported. Energy is measured in terms of kWh, kVarh. Max demand current can be measured over preset periods of up to 60 minutes. It also has dual tariffs function. It is an idea product for application that have two power sources . With 230VAC signal, the meter can shift the measurement from T1 to T2.

    In order to measure energy, the unit requires voltage and current inputs in addition to the supply required to the power the meter. The required current inputs are obtained via current transformers. This meter can be configurable to work with a wide range of CTs, giving the unit a wide range of operation. Build-in interface provides pulse, RS485 Modbus RTU outputs and the 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
    Reset for demand measurements
    Pulse output duration 

    Two pulse output indicates real-time energy measurement. An RS485 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

     RS485 Serial – Modbus 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 for active energy is 3200imp/kWh. The pulse width for pulse 1 can be set from the set-up menu.
