1. Introduction
The SDM54 measures and displays the characteristics
of single phase two wires (1p2w) and three phase four
wires(3p4w) supplies, including voltage, frequency, current,
power, power factor, active and reactive energy, imported
or exported.
Energy is measured in terms of kWh and kVArh. Maximum
demand on power and current can be measured over
preset periods of up to 60 minutes. SDM54 supports max.
100A direct loads per phase, with dual tariff management
availability. The meter is designed for DIN-rail mounting,
with IP51 front protection. The meter is optionally
equipped with pulse outputs, RS485 Modbus port or
M-bus port. Configuration can also be done via keypad,
which is password protected.
1.1 Unit Characteristics
The SDM54 Series are smart three phase energy meters,
covering 3 models with following features and differences:

1.2 RS485 Serial–Modbus RTU
The RS485 serial port with Modbus RTU protocol provides
a means of remotely monitoring and controlling the unit.
Set-up screens are provided for setting up the RS485
port. D/LT645 protocol is optionally available on request.
1.3 M-Bus
The M-Bus port complying with EN13757-3 protocol
provides a means of remotely monitoring and controlling
the meter. Set-up screens are provided for setting up the
M-Bus port.
1.4 Pulse outputs
Two pulse outputs that clock up the 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.
1.5 Double Tariffs
The meter has double tariffs function for the cost allocation
management. There are two terminal to monitor voltage
input from external device. Once there are voltage
detected within 230V (80~120%), the energy will be
counted in another registers.
2. Start-up Screens
The interface performs
initial testing.
The second screen
indicates the software
version.
Meter serial number;
Modbus ID; Baudrate
info are provided.
After a short delay, the screen will display active energy
measurements.
