Introduction
The SDM630MCT-MV measures and displays the characteristics of single phase two wire (1p2w),
three phase three wire (3p3w,) and three phase four wire (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. The requisite current input(s) are obtained via
current transformers(CT).
SDM630MCT-MV 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.
This unit can be powered from a separate auxiliary (AC or DC)supply. Alternatively it can be
powered from the monitored supply, where appropriate.
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 with 0.333V output. The secondary CT is fixed
0.333V, and the primary is optional.
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.
