Introduction
The SDM530CT-Modbus measures and displays the characteristics of 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.
SDM530CT-Modbus can be configured to work with a wide range of CTs, giving the unit a wide
range of operation. Built-in interfaces provides pulse and RS485 Modbus RTU .Configuration is
password protected.
Unit Characteristics
The Unit can measure and display:
Line voltage
Line Frequency
Currents, Current demands
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
Demand Interval Time(DIT)
Reset for demand measurements
Pulse output duration
Two pulse output indicate 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 1000imp/kWh, its width is fixed at 100ms.
The default constant of configurable pulse output 1 is 100imp/kWh. default pulse width
is100ms.The configurable pulse output 1 can be set from the set-up menu.
