necessitate further measures. However, it does contain information which must be read for your
personal safety and to avoid material damages. This information is highlighted by a warning triangle
and is represented as follows, depending on the degree of potential danger.
Warning
This means that failure to observe the instruction can result in death, serious injury or
considerable material damage.
Caution
This means hazard of electric shock and failure to take the necessary safety
precautions will result in death, serious injury or considerable material damage.
Qualified personnel
Operation of the equipment (module, device) described in this manual may only be performed by
qualified personnel. Qualified personnel in this manual means person who are authorized to
commission, start up, ground and label devices, systems and circuits according to safety and
Regulatory standards.
Use for the intended purpose
The equipment (device, module) may only be used for the application specified in the catalogue and
the user manual, and only be connected with devices and components recommended and approved
by Eastron Electronic.
Proper handling
The prerequisites for perfect, reliable operation of the product are proper transport, proper storage,
installation and assembly, as well as proper operation and maintenance. When operating electrical
equipment, certain parts of this equipment automatically carry dangerous voltages. Improper
handling can therefore result in serious injuries or material damage.

1.2 Foreword
the Eastron SDM530D DIN rail three phase four wire energy meter. The Eastron SDM530D energy
meter is the most advanced type electronic kWh meter available at the market. With the Eastron
product range we have introduced a large scale of energy meters on the market suitable for 110V AC
to 400V AC (50 or 60Hz).
The Eastron SDM530D has two versions, direct connection version and CT connection version. The
direct connection version SDM530D can be connected to load up to 100A. While the SDM530D CT
version shall be connected with 5A secondary output current transformer. The CT ratio can be
programmable via the buttons on the front panel.
The meter adopts big size LCD display with a highlight blue color backlit. The backlit has 3 modes
(always on, always off, on for 30seconds after each button click) programmable from the front button.
With high accuracy and long lifespan design, the SDM530D is a perfect option for any three phase
applications. 18 month quality warranty is offered, Eastron is responsible for replacement of any
failure meters, which caused by production or design mistake.

1.8 Operating
Consumption indication
On the SDM530D’S front panel, there are four LED, in which three LED are for three phase voltage and
another one for impulse. The constant of the impulse is shown on the nameplate of the meter.
Reading the meter
The SDM530D energy meter is equipped with 6+1 or 5+2 LCD display, which is used as recording
consumption and can’t be reset to zero. The number system is based on units of 10. And unit is kWh.
On the front panel, there are two rubber buttons, which are used to scroll down the meter display
information.
Pulse output
SDM530D series DIN rail energy meter is equipped with a pulse output which is fully separated from
the inside circuit. That generates pulses in proportion to the measured energy. They are test pulse
output (pins 8 & 9). Usually, the test pulse output is used as testing accuracy or reading purpose in
close quarters.
The test pulse output is a polarity dependant, passive transistor output requiring an external voltage
source for correct operation. For this external voltage source, the voltage (Ui) should be 5-27V DC,

Three phase din rial meter SDM530D user manual
and the maximum input current (Imax) should be 27mA DC. To connect the impulse output, connect
5-27V DC to connector 9 (anode), and the signal wire (S) to connector 8 (cathode). The meter pulses
is indicated on the front panel.
LEDs
There are four LEDs on the front panel, they are marked with A B C and imp/kwh.
A B C are phase voltage missing indicators , and imp/kwh is pulse output indicator.

Backlit Setting
SDM530D is equipped with highlight blue color backlit, which provide a clear view of reading
when the meter is installed in a dark condition.
There are three modes optional:

1.9 CT Ratio setting (SDM530D CT only)
The SDM530D CT measure the secondary energy consumption via external current transformer.
If the user wants to read the primary energy reading, he can program the CT ratio to the meter
by the front buttons. The meter has 27 pre-set and common CT ratios optional to the user.
