In the standard version, the chargers are equipped with an RS-232 communication interface. In the case
of ordering a charger with the RS-485 interface, it is mounted instead of the RS-232. The chargers can coop-
erate with external RS-232/Ethernet converter modules, but they require a separate order and are delivered
in separate packaging containing their own set of documents.
For the remote control and operation of the charger, please, use the MERAWEX software - offered as a
separate product (not included in standard).

2. METHOD OF OPERATION
2.1.1. General
The power system is supplied by single-phase mains and generates stabilized voltage at its output(s). A
voltage on battery bank is maintained by the power system at the level of full charge depending on the type
and required value of temperature compensation. It provides battery protection against excessive discharge
that may lead to permanent damage. The power system features sound and visual indication of an operation
mode and generates alarm indications and is equipped as standard with a communication link.
2.1.2. Block diagram
Fig. 3 Block diagram of SI48-1U-16 power system
The main power blocks converting the mains voltage into stabilized output voltage are two parallel-coop-
erating rectifier blocks # 1 and # 2 –cooperating in parallel. The SI48-1U-8 charger has only one rectifier. Each

of the rectifiers is a standalone power conversion block equipped with its own power factor correction (PFC)
system enabling to obtain the input cosφat a level higher than 0.95. Behind the power equalizer block, in each
rectifier, there is a DC / DC converter which reduces and stabilizes the output voltage. This converter also
provides galvanic isolation between the mains and the output circuits.
Both rectifiers cooperate in parallel, dividing output power between them. The advantage of such a solu-
tion when the load is below the nominal one is: operation of rectifiers in better conditions (lower power of the
own losses), and at low loads, operation even when one of the rectifiers is faulty. The controller monitoring
their cooperation limits the total output power to 800 W.
The power distribution packet is responsible for supplying power to the both outputs (OUT 1 and OUT 2)
of the charger from the rectifiers’ outputs (in the mains operation mode) or from the battery (in the battery
operation mode). The actual operating mode is indicated by activation of the POWER or BATTERY LED diode.
In addition, while charging the battery, this fact is indicated by the CHARGE LED being on when the bulk
charging happens or by its blinking when the charging is in the floating mode. On the packet there are two
independent LVDD devices in the both BAT 1 and BAT 2 battery circuits protecting against possible fault of
each cooperating battery. In each of the circuits (both two output circuits and two battery ones) there are fuses,
the failure of which is indicated by an individual LED diode. This signaling is also repeated by generating an
appropriate alarm, however, in the event of a blow of any of the output fuses, the general alarm, regarding the
fuse in the output circuit, is generated.
A battery test of lowering the output voltage and bringing the current from the battery is performed peri-
odically. During this time, both the acceptable voltage drop and the current difference between the batteries
are checked (if the both batteries are connected). The difference in currents between batteries is also checked
in other charger operation modes.
All alarms are signaled locally (LED diodes, LCD display and acoustic signal) and remotely via three output
signals.
The INTERFACE controls the distribution of measurement and control signals, appropriate adjustment of
their levels, distribution of power for the measurement subsystems and separation of circuits, for which the
galvanic isolation should be maintained. The basic measurement signals of voltage value UOUT,UB1,UB2 and
current value IOUT,IB1,IB2 and ambient temperatures of batteries and the interior of the charger are directed to
the INTERFACE. These signals, after reinforcement and normalization, form the basis for the evaluation of
the charger operation by its internal microprocessor controller. The controller also receives fault signals, e.g.
of each of rectifiers and fuses in the output and battery circuits.
The controller, via the INTERFACE, regulates the output voltage of the rectifiers and returns information
about their powering, internal temperature or possible fault. In addition to the operation of internal alarm sig-
nals, the system is adapted to accept two signals of external alarms (EXT FLT #1 and EXT FLT #2) requiring
shorting of contacts located on the potential of the positive rail of the charger. Consequently, the controller
issues the signals controlling signalization relays ALARM URGENT (ALARM),ALARM (WARNING), and
MAINS FAULT. These signals are provided in the form of potential-free switchable relay contacts isolated from
all other circuits, from which normally open or normally closed contacts can be used. Assigning individual
events in the charger to their signalization as an urgent alarm or non-urgent alarm, and thus making a decision
whether an event is to be acoustically signaled (only urgent alarms) is possible at the production stage or as
part of a factory service. The user can do this alone using the monitoring software sold separately.
The controller records the history of events (about 400 last ones) which has occurred in the charger,
readable via the COM communication interface, which is normally made as the RS232 port.
On the front panel there is an LCD liquid crystal display, 3½ digits, enabling the reading of the charger
parameters: output voltage, output current, battery current, temperature and alarm code (4.2.3) in case of its
occurrence. Switching between the type of displayed measurement or viewing an error number is possible by
means of the button next to the display. In addition, some alarm states (urgent alarms only) are signaled
acoustically. Canceling the acoustic alarm is possible by pressing the CLEAR button.
The socket at the back of the charger described as TEMP SENSOR allows you to connect a temperature
sensor to measure the temperature of the battery. On the basis of the measured temperature, the charger’s
controller adjusts the floating voltage of the battery bank and generates an alarm if its operating temperature
limits are exceeded. If the sensor is not connected, the charger sets the default value of floating voltage for
the temperature of 25qC and does not perform temperature compensation.
The basic, factory-set electrical settings are included in the item 1.2.3 Technical information, Electrical
parameters. The default (factory) assignments of events to the type of alarms have been described below. The
local signaling alarm codes are presented in the item 4.2.3.

sulation is not shunted by any resistor (group of resistors) or any capacitor (group of capacitors).
The contacts of the remote signaling relays and the COM link are completely isolated from all circuits (includ-
ing output ones).
Appropriate amounts of electrical insulation resistance are given in section 2.2.2.
The power plant and its rectifier units used in the device are equipped with Y2 class anti-interference capaci-
tors. The leakage current in the protective conductor can reach 3 mA.
NOTE: For a telecommunications system, the positive pole of the gym must be connected to the metal struc-
ture of the housing:
a. Directly by connecting any "plus" output screw terminal to the gym ground terminal; this connection is not
made at the factory;
b. indirectly by connecting a separate yellow-green wire of any "plus" output screw terminal to the grounded
positive rail of the telecommunication DC switchboard.

OUT 2. Each circuit is protected by a fuse located in the fuse holder at the front panel. Blown out fuses are
indicated with a LED located by the fuse holder of a specific output circuit. Load shall be connected with a
max. 6 mm2conductor (the limitation applies to the assembly coupling).
3.2.5. Connection of a temperature probe
SI48-1U power system provides a dependence of output voltage value in floating mode to the ambient
temperature. The end of a temperature probe is located by the battery, and the MINI-JACK socket at the other
end of a cable is connected to TEMP SENSOR (temperature probe) socket at the back panel.
3.2.6. Connection of alarm signals
Outputs marked as ALARM, WARNING and MAINS FAULT are switchable relay contacts separated from
power system circuits. Since all the sockets are connected to the relay contacts, a correct use of double pins
enables use of NO and NC contacts.
All connections require 0.5mm2y1mm2conductors with COMBICON (PHOENIX) pins.
3.2.7. Connection of external alarm signals
The power system maintains 2 external two-state signals at EXT FLT #1, EXT FLT #2 outputs, each with
the positive bus potential. Alarm is generated at a short circuit of a specific line with a positive bus. All connec-
tions require 0.5mm2y1mm2conductors with pins.
3.2.8. Connection of external communication
Back panel features 6/6 RJ12 type COM socket providing external digital communication with a power
system. Power system features RS232 module or optional RS485 module. Depending on the module used,
signals are transmitted as specified below.

4. OPERATION
4.1. Power plant operation mode indication
4.1.1. Local indication
LCD displays current output voltage. Pressing the button several times changes the displayed information:
output current, battery current, temperature and information on the cause of alarm (alarm code), if present.
Another press of the button causes the output voltage to be displayed. Type of currently displayed information
is indicated by a LED on the left side of the display.
Front panel features LEDs indicating a system operation mode (POWER,BATTERY,CHARGE and alarm
event (ALARM,WARNING,EXT FAULT).
Urgent alarms are indicated by a sound indication. Sound indication is switched off by pressing CLEAR
button on the right side of LEDs. Pressing the button for more than 5 sec. causes the alarm to be reset,
although the alarm indication can be permanently reset when alarm cause is removed.
LEDs at the front panel by the fuse holders indicate blown out fuses of a specific circuit.
Details of local indication of each operation mode are presented below, and the method of alarm event
indication (local and remote) depends on the configuration - default (factory) assigned indications concerning
specific causes are presented in item 4.2.3.

User manual SI48-1U 0310.00.95-01.1 23/24
Detailed diagnostics and change of power system settings are carried out by a manufacturer via a digital
socket without intervention inside the device. Optional software enables diagnostics and change of power
system settings.
4.2.1. Verification of power system configuration
At power-up, power system recognizes current operation mode, i.e. detects number of connected batteries
and the presence of a temperature probe. Verification of power system configuration is confirmed by a single
audible signal.
If detected configuration differs from the default, a warning is generated (indicated by the LED at the front
panel and the remote indication socket).
4.2.2. Indication of local alarm cause
LCD displays current output voltage, and pressing the button changes the display to an output current,
battery current, temperature and alarm cause, if present.
All detected alarm events and displayed codes are indicated below.
