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.
The Unit can measure and display:
Line voltage and THD% (total harmonic distortion) of all phases
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:
Supply system selection 1p2w, 3p3w,3p4w
Demand Interval Time(DIT)
Reset for demand measurements
Two pulse output indicates real-time energy measurement. An Mbus output allows remote
monitoring from another display or a computer.
This uses an MBus port with EN13753-3 protocol to provide a means of remotely monitoring and
Set-up screens are provided for setting up the MBus port.
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.
