Introduction
The SDM630-2T 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.
SDM630-2T 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
provide pulse and RS485 Modbus RTU or M-bus 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 Modbus or M-Bus 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.
Mbus
This unit 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

The unit provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total /
import/export kWh or kVarh.
The pulse constant can be set to generate 1 pulse per:
dFt = 2.5 Wh/VArh
0.01 = 10 Wh/VArh
0.1 = 100 Wh/VArh
1 = 1 kWh/kVArh
10 = 10 kWh/kVArh
100 = 100 kWh/kVArh
Pulse width: 200/100/60ms
Pulse output 2 is non-configurable. It is fixed up with active kWh. The constant is 400imp/kWh.
