    SDM630MV CT-2C measures and displays the characteristics of two three phase four wires circuits or 6 single phase circuits, including voltage, frequency, current, power and 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 with 0.333V output, giving the unit a wide range of operation. Built-in interfaces provides pulse and RS485 Modbus RTU outputs. Configuration is password protected.

     Unit Characteristics
    The Unit can measure and display electronic information of multi-channels 
    L-N 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 1phase2wire, 3phase 4wires
    CT1 value
    PT ratio (1 to 9999)
    Demand Interval time
    Reset for demand measurements
    Pulse output duration 

    A 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 Primary Current.
    The secondary CT is fixed at 0.333V
     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 2 pulse outputs referring the energy consumption of two circuits. Both pulse outputs are configurable. The pulse width for active energy can be set from the Set-up menu.
