Introduction
SDM630MV-2L Dual Load measures and displays the characteristics of two three phase four wires
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 has two RJ12 sockets for fast connecting with current transformer CTs with 0.333V
output. This meter also provides 1 digital output ( solid state) with capability to command most
of the circuit breaker coils directly.
Unit Characteristics
The Unit can measure and display:
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 3phase 4wires
CT1 value
PT ratio (1 to 9999)
Demand Interval time
Reset for demand measurements
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.

The second screen indicates the firmware
installed in the unit and its build number.
3
Next the unit performs a self-test and
indicates if the test passes.
After a short delay, the screen will display active energy measurements.
Measurements
The SDM630MV-2L measures all important electrical parameters, which is shown on the LCD
display and approachable via RS485. On the front panel there are four sensitive buttons and two
LED indicators.
The buttons operate as follows:
1
Selects the Voltage and Current display screens
In Set-up Mode, this is the “Left” or “Back” button.
Long Press for 3s to change the shift “C1” circuit information to “C2” circuit
information
2
Select the Frequency and Power factor display screens
In Set-up Mode, this is the “Up” button
3
Select the Power display screens
In Set-up Mode, this is the “Down” button
4
Select the Energy display screens
In Set-up mode, this is the “Enter” or “Right” button
There are two LED indicators on the front panel, namely Pulse1 and Pulse2. Pulse 1 is for total

active energy of C1 circuit, and Pulse 2 is for total active energy of C2 circuit. Pulse constant is
1000imp/kWh.
The unit can measures and displays data of two three phase circuits: C1 circuit and C2 circuit. If
C1 LED shows, that means the reading on the LCD are for C1 circuit. While C2 is there, it means
the measurements on the LCD are for C2 circuit.
The default display after the meter is power on, the LCD show “C1” circuit information. The way
to shift “C1” circuit information to “C2” circuit information is by pressing the “U/I” button
for 3s. If the meter are showing “C2”, and the user wants to shift it to be “C1” circuit,
Then he shall keep pressing the “U/I” button .
