Introduction
The SDM530-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. Max. 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.
SDM530-Modbus supports max. 100A direct connection, saving the cost and avoiding 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
Line Frequency
Currents, Current demands
Power, maximum power demand and power factor
Imported and exported active energy
Imported and exported reactive energy
The unit has password-protected set-up screens for:
Changing password
Setting demand Interval Time(DIT)
Resetting for demand measurements
Pulse output duration
Two pulse outputs indicate real-time energy measurement. An RS485 output allows remote
monitoring from another display or a computer.
RS485 Serial - Modbus RTU
This unit has 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
SDM530-Modbus 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), and the pulse
width is fixed 100ms.
The default constant of configurable pulse output 1 is 400imp/kWh, and default pulse width is
100ms.The configurable pulse output 1 can be set from the set-up menu.
