Introduction
The SDM630-Modbus MID 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-Modbus MID 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 provide pulse and RS485 Modbus RTU 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. An RS485 output allows remote
monitoring from another display or a computer.
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
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.

Start-up Screens
1
The first screen lights up all display
segments and can be used as a display
check
2
The second screen indicates the firmware
installed in the unit and its build number.

Set-up
To enter set-up mode, pressing the button for 3 seconds, until the password screen
appears.
Setting up is password-protected so you must enter the correct password (default ‘1000’) before
processing. If an incorrect password is entered, the display will show: Err
To exit setting-up mode, press repeatedly until the measurement screen is restored.
Set-up Entry Methods
Some menu items, such as password, require a four-digit number entry while others, such as supply
system, require selection from a number of menu options.
Menu Option Selection
1) Use the and buttons to select the required item from the menu. Selection does
not roll over between bottom and top of list
2) Press to confirm your selection
3) If an item flashes, then it can be adjusted by the and buttons. If not, there
maybe a further layer.
4) Having selected an option from the current layer, press to confirm your selection. The
SET indicator will appear.
5) Having completed a parameter setting, press to return to a higher menu level. The SET
indicator will be removed and you will be able to use the and buttons for further
menu selection.
6) On completion of all set-up, press repeatedly until the measurement screen is restored.
