A pulse output indicates real-time energy measurement. An RS485 output allows remote monitoring from another display or a computer.
The Unit can measure and display electronic information of
multi-channels:
The unit has password-protected set-up screens for:

• 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
• Changing password
• Supply system selection 1phase2wire, 3phase 4wires
• CT Ratio (1 to9999 )

• Pulse output duration
Introduction
SDM630MCT-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 congured to work with a wide range of CTs, giving the unit a wide range of
operation. Built-in interfaces provide pulse and RS485 Modbus RTU outputs. Conguration is
password protected.

RS485 Serial – Modbus RTU
The unit can be congured to operate with CT ratio between Pri-
mary Current and Secondary Current. The secondary CT has two
options: 1A / 5A
This provides 2 pulse outputs referring the energy consumption of two circuits. Both pulse outputs are congurable. The pulse width for active
energy can be set from the Set-up menu.
This uses an RS485 serial port with Modbus RTU protocol to pro-
vide a means of remotely monitoring and controlling the Unit.
Set-up screens are provided for setting up the RS485 port.

Measurements
The SDM630MCT-2C 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 four LED indicators.
The buttons operate as follows:

MerCs Strider M6 ME-PM-63OMCT-2C
There are four LED indicators on the front panel , namely C1, C2, Pulse1 and Pulse2.
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 in-
formation is by pressing the “Down” button. If the meter are showing “C2”, and the user want to shift it to be “C1” circuit, Then he shall keep
pressing the “UP” button.

The PT option sets the secondary voltage (PT2 100~500V) of the Voltage transformer (PT) that wires to the meter and the PT ratio between PT1 to
PT2. The default value is 400V for Secondary PT (L-L), and the ratio between PT1 and PT2 is 1.
Example: if set the ratio to be 100, that means the primary current is secondary current x100.
