Introduction
The SDM630-Mbus V2 measures and displays the characteristics of single phase two wires (1p2w),
three phase three wires (3p3w,) and 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.
SDM630-Mbus V2 supports max. 100A direct connection, saves the cost and avoid the trouble to
connect external CTs, giving the unit a cost-effective and easy operation. Built-in interfaces
provides pulse and Mbus outputs. Configuration is password protected.
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(DIT)
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.
Mbus
This uses an MBus port with EN13753-3 protocol to provide a means of remotely monitoring and
controlling the Unit.
Set-up screens are provided for setting up the MBus 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 400imp/kWh (unconfigurable), its width is fixed at 100ms.
The default constant of configurable pulse output 1 is 400imp/kWh, default pulse width is
100ms.The configurable pulse output 1 can be set from the set-up menu.
