2. Technical description.
2.1. General description.
The buffer power supply has been designed in accordance with the requirements of the PN-EN 50131-6
standard, grade 1÷3 and II environmental class. It is intended for an uninterrupted supply to alarm system devices
requiring stabilized voltage of 12V/DC (+/-15%).
Depending on a required protection level of the alarm system in the installation place, the PSU efficiency
and the battery charging current ought to be measured as follows:
* Grade 1, 2 - standby time 12h
Output voltage 1,4A + 1,5A battery charge
** Grade 3 - standby time 30h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 – PN-EN 50131-1).
Output voltage 0,56A + 1,5A battery charge
- standby time 60h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 – PN-EN 50131-1).
Output voltage 0,28A + 1,5A battery charge
*** General use – if the PSU is not mounted within an installation which is PN-EN-50131 compliant, the
acceptable current efficiency amounts to:
1. Output voltage 3A + 0,2A battery charge
2. Output voltage 2,6A + 0,6A battery charge
3. Output voltage 2,2A + 1A battery charge
4. Output voltage 1,7A + 1,5A battery charge
Total current of the receivers + battery: 3,2A max.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal
enclosure (colour: RAL 9005 - black) which can accommodate a 17Ah/12V battery. It features a micro switch that
indicates unwanted door opening (faceplate) and detaching from the mounting surface.
2.2. Block diagram.
The PSU has been manufactured based on a high-duty system of DC/DC converter. It features a
microprocessor-based operation control, responsible for full diagnostics of the PSU and battery parameters.

3.3.3 Screen – history of the PSU’s parameters.
During normal operation the PSU records the electrical parameters delivered to the AUX output and saves
them in its non-volatile memory. The saving occurs every 5 minutes and the internal memory can store up to about
6100 values. The memory works in a circular cycle. When the memory becomes fulfilled, the oldest entries get
replaced with the newest ones.
The screen of the parameters history enables reading of the stored parameters and scanning the values on
a chart. The screen features a time axis, located horizontally in the bottom part of the chart, and the axis of a
selected parameter – located vertically in the left part. The cursor can be moved into various time points via ‘<’ and
‘>’ buttons. For each time point, the corresponding value in can be read.
Fig. 8. Screen of the history of PSU’s parameters.
From the given chart entries, the values of the following parameters can be read:
- Uaux
- output voltage (approximate value within 5 minute period)
- Uaux max
- maximum output voltage
- Uaux min
- minimum output voltage
- Iaux
- output current (approximate value within 5 minute period)
- Iaux max
- maximum output current
- Iaux min
- minimum output current
For optimal reading and analysis of the values shown on the chart, the time range of the chart screen can
be adjusted in the bottom axis. Here are the available ranges:
<8h>
<24h>
<2days>
<week> (weekly)
In order to change the displayed parameter, highlight its name by pressing the ‘SET’ button. Then, with the
‘<’ and ‘>’ buttons choose the requested measurement. Pressing the ‘SET” button again will highlight the time
range of the chart, which can be changed with the ‘<’ and ‘>’ buttons. Another pressing of the ‘SET’ button will
enable moving the cursor (vertical dotted line on the chart) along the time line with the ’<’ and ‘>’ buttons. The
values of currently chosen parameter and the register time pointed by the cursor will also be highlightened,
3.3.4 Screen – failure history.
If any incorrect electrical parameters appear during the operation, the PSU will begin indicating the failure
by cyclical switching on and off the LCD display illumination, illuminating the failure LED on the panel and activating
the acoustic indication (provided, it has not been switched off).
The screen of the PSU failure history enables overviewing the events recorded by the internal diagnostic
system. The memo can store over 2000 events carrying information about the fault type, time of occurrence and
values of the voltages or load current. Additionally, on the basis of the stored parameters, the diagnostic system
assigns the fault code characteristic for a particular event.
The operation history can be previewed by pressing ’<’ or ‘>’. It can be done in two modes: short (date,
time, code, fault description) or full - with additional information about values of voltages and current, and status of
inputs and outputs. Switching between the modes is to be done by the ‘SET’ button.

3.6 Technical outputs.
The PSU feature indication outputs, with galvanic isolation, which change state if any of the following event
occur:
•
EPS FLT – output indicating AC power loss.
The output indicates AC power loss. Under normal status – with the 230V AC supply, the output is
close. In case of a power failure the PSU will switch the output into the open state after a period of time
determined by the ‘EPS output lag’ facility (see 3.4.2, table 7).
•
APS FLT - output indicating battery failure.
The output indicates a failure in the battery circuit. Under normal status (during correct operation) the
output is close. In case of a failure the PSU will switch the output into the open state. Any failures can be
triggered by the following events:
- a faulty or undercharged battery
- battery voltage below 11,5V during battery-assisted operation
- battery fuse fault
- no continuity in the battery circuit
•
PSU FLT - output indicating PSU failure.
The output indicates the PSU failure. Under normal status (during correct operation) the output is close.
In case of a failure the PSU will switch the output into the open state. Any failures can be triggered by the
following events:
- low output voltage Uaux<11,8V
- high output voltage Uaux>14,7V
- high battery voltage Uaku>14V (during battery test)
- failure of the battery charging circuit
- polymer fuse PTC activation
- exceeding the PSU nominal current
- failure in the battery charging circuit
- activation of the over voltage protection OVP
The technical outputs have been implemented with galvanic isolation between the PSU’s systems and the
attached devices.

•
TAMPER - output that indicates tampering with the PSU enclosure: output with volt-free (potentialfree) contacts indicating the door status and PSU detachment from the mounting surface. NC contacts: the
PSU is locked and fixed to the dedicated surface.
3.7 Input of collective failure: EXT IN.
The EXT IN (external input) technical input indicating a collective failure is intended for additional, external
devices that generate the failure signal. If voltage appears at the EXT IN input, it will cause generating a PSU
failure, storing the information about the event in the internal memo and sending the signal about the failure to the
PSU FLT output.
The EXT IN technical input has been implemented with galvanic isolation between the PSU’s systems and the
devices attached.
Fig. 16. Electrical diagram of the EXT IN input.
The electrical diagram below shows the way of connecting external devices to the EXT IN input. Outputs
such as: OC (open collector), relay type or tamper may be used as a source of the signal.
Fig. 17. Examples of connections.
In the option with tamper switches, the VEXT jumper must be on. It polarises the EXT IN input circuit
therefore is required in such configuration.
The EXT IN input has been adjusted to cooperate with fuse modules that generate a failure signal in case
of a fuse fault in any of output sections (e.g. AWZ535, AWZ536). To guarantee a correct cooperation between the
module and the EXT IN input, the VEXT jumper must be on and the connections are to be made accordingly to the
diagram below.
Fig. 18. Example of a connection with the fuse module AWZ535 or AWZ536.

4. Battery-assisted operation.
4.1. Running the PSU from the battery.
The PSU has been equipped with two buttons on the pcb board which enable running or disconnecting the
PSU during battery-assisted operation.
• Running the PSU from the battery: press the START button on the main board and hold for 1s.
• Disconnecting the PSU from the battery: press the STOP button on the main board and hold for 5s.
4.2. Deep discharge battery protection UVP.
The PSU is equipped with the disconnection system and the discharged battery indication. If the voltage at
the battery terminals drops below 10V±0.2V during battery-assisted operation, the battery will be disconnected
after appr.15s.
Switching off/on the function of the battery protection:
Press the ‘SET’ button from the level of the LCD desktop and then choose:
”PSU -> Battery protection: YES/NO” (see chapter 3.4.2, table 7).
Caution.
Deactivating of the UVP function is not recommended since a deep discharge of the battery limits its
capability of storing energy, lowers its capacity and shortens its durability.
4.3 Dynamic battery test.
The PSU runs a battery test every 10 minutes. It is done by a momentary switching into a battery-assisted
operation. A failure is indicated when voltage drops below 12V. The battery test facility can be switched off.
Deactivating/activating the test:
- enter the PSU settings from the level of the LCD desktop by pressing the ‘SET’ button. Then choose:
”PSU -> Battery protection: YES/NO” (see chapter 3.4.2, table 7) or
- from the pcb level: during mains-powered PSU operation press the STOP button on the main board and
hold it for 3 seconds.
The device will confirm the activation/deactivation of the test (see tab.8 [6, 7]) and show an appropriate
message on the display: ”TEST ON/ TEST OFF”.
Deactivating/activating the test is stored in the memory even after unplugging the device from
mains. The battery failure indication at the APS FLT output is automatically switched off. The
battery protection system against deep discharged remains on, though.
4.4. Standby time.
The standby time during batter-assisted operation depends on: battery capacity, battery charge level and
load current. In order to keep the standby time, the current drawn from the PSU during battery-assisted operation
should be limited. Characteristics for a 17Ah/12V SLA:
Grade 1, 2 - standby time 12h
Output current 1,4A + 1,5A battery charge
Grade 3 - standby time 30h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 – PN-EN 50131-1).
Output current 0,56A + 1,5A battery charge
- standby time 60h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 – PN-EN 50131-1).
Output current 0,28A + 1,5A battery charge
23

PSBEN3012C/LCD
4.5. Battery charging time.
The PSU has a battery circuit charged with direct current. The current selection is done via IBAT jumpers.
The table below shows how long it takes to charge a (fully discharged) battery up to min. 80% of its nominal
capacity.

4.6 Operation without a battery.
In case of an expected PSU operation without an attached battery, make a necessary configuration setting
from the level of the LCD desktop (see chapter 3.4.2, table 7).
”Settings -> PSU -> Battery present: YES/NO”
In this mode the automation system allows adjustments of PSU’s output voltage without indicating a failure
connected with working of the battery.
CAUTION. During operation without battery assistance the PSU does not perform any parameter
control that monitors its proper operation. Therefore, this mode ought to be chosen thoughtfully.

5. Remote monitoring (option: Wi-Fi, Ethernet, RS485, USB).
The PSU has been adjusted to operate in a system that requires a remote control of the parameters in a
monitoring centre. Transmitting data concerning PSU status is possible due to an additional, external
communication module that is responsible for communication in Wi-Fi, Ethernet or RS485 standard. A USB-TTL
interface enables connection between the PSU and a computer.
5.1 Communication in WI-FI wireless network.
WI-FI wireless communication can be implemented on the basis of the additional WI-FI ”INTWF” interface
which works within the frequency range of 2,4GHz accordingly to the IEEE 802.11b standard. The interface shall
be mounted in a selected location, inside the enclosure so that the aerial protrudes outwards.
A great advantage of wireless communication is lack of additional cords and fast development or
modification of the network’s structure.
Fig. 19. WI-FI communication with the use of the WI-FI ”INTW” interface.
5.2 Communication in ETHERNET network.
Communication in the Ethernet network is possible due to the additional Ethernet ”INTE” interface compliant
with the IEEE802.3 standard, featuring a built-in connection socket RJ45. This interface features full galvanic
isolation and protection against surges.
Fig. 20. Ethernet communication with the use of the Ethernet ”INTE” interface.
5.3 Communication in RS485 network.
Another kind of network communication is the RS485 that uses a two-wire transmission line. To implement
this kind of data exchange, the PSU needs to be equipped with the additional RS485-TTL ”INTR” interface which
converts data from the PSU into the RS485 standard and the USB-RS485 ”INTUR” one that converts data from the
RS485 network into a USB. These interfaces feature full galvanic isolation and protection against surges.
25
www.pulsar.pl
PSBEN3012C/LCD
Fig. 21. RS485 communication with the use of the interfaces: ”INTR” and ”INTUR”.
5.4 USB-TTL communication.
If the PSU does not cooperate with any of previously mentioned network and the access to the parameters’
adjustment and memo readings are necessary, the USB-TTL ”INTU” needs to be used. This interface allows direct
connection between the computer and the PSU and it is recognisable by the operating system as a virtual COM
port.
Fig. 22. USB-TTL communication with the use of the USB-TTL ”INTU” interface.
5.5 ”Power security” program.
”Power security” is a computer program that has been created for displaying and analysing the information
sent from the PSU installation spots. Here is its front panel:
Fig. 23. Front panel of “Power security” program.
26
www.pulsar.pl
PSBEN3012C/LCD
The main panel of the program has been formulated in such a way that it is possible to divide it into smaller
areas, depending on the number of power supplies.
The program enables both a visualisation and an analysis of the received data. Exceeding of the acceptable
parameters is indicated by highlighting in red the appropriate area or by twinkling of the indicator. Particular tabs
contain a chart with an overview of the PSU parameters and failure memo along with the information about status
and the electrical specifications of the technical outputs.
The ”Power Security” program is available on our website: www.pulsar.pl
Its detailed description can be found in the manual of the program.

7. Installation.
7.1 Requirements.
The buffer PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable
and required for a given country) for 230V/AC interference and low-voltage installations. The unit should be
mounted in confined spaces, in accordance with the II environmental class, with normal relative humidity (RH=90%
maximum, without condensation) and temperature from -10°C to +40°C. The PSU shall work in a vertical p osition
that guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
As the PSU is designed for a continuous operation and is not equipped with a power-switch, therefore an
appropriate overload protection shall be guaranteed in the power supply circuit. Moreover, the user shall be
informed about the method of unplugging (most frequently through separating and assigning an appropriate fuse in
the fuse-box). The electrical system shall follow valid standards and regulations.
7.2 Installation procedure.
CAUTION!
Before installation, cut off the voltage in the 230V power-supply circuit.
To switch off power use an external switch in which the distance between the contacts of all poles in the
disconnection state is not less than 3mm.
1. Mount the PSU in a selected location. It is crucial to bolt the tamper grip to the mounting surface. The grip
is located in the central part of the enclosure (see fig. 3 [7]) and guarantees indication in case of any
attempts of detaching the device from the mounting surface. Proper installation is one of the requirements
of the PN-EN 50131-6 standard.
Fig. 24. Fixing a tamper grip.
2.Connect the power cables (~230Vac) to L-N terminals of the PSU. Connect the ground wire to the terminal
marked by the earth symbol: PE. Use a three-core cable (with a yellow and green PE protection wire) to make the
connection. Lead the cables to the appropriate terminals through the insulating bushing.
The shock protection circuit shall be performed with a particular care, i.e. the yellow and green wire coat
of the power cable shall stick to one side of the terminal - marked with the PE symbol on the PSU
enclosure. Operation of the PSU without the properly made and fully operational shock protection circuit
is UNACCEPTABLE! It can cause a device failure or an electric shock.
3. Connect the receivers’ cables to the +AUX, -AUX connectors of the terminal block on the PSU board.
4. If necessary, connect the device’s leads to the technical inputs and outputs:
- EPS FLT; technical output of AC power loss indication (alarm panel, controller, indicator, etc.)
- PSU FLT; technical output of the PSU failure.
- APS FLT; technical output of the battery failure.
- TAMPER; output indicating enclosure opening or detaching from the assembly surface.
- EXT IN; collective failure output
5. With the IBAT jumper determine the maximum battery charging current, in accordance with the battery
parameters.
6. From the level of the LCD panel decide whether the function of discharged battery disconnection U<10 V (+/-5%)
is to be on or off (see chapter 3.4.2).
29
www.pulsar.pl
PSBEN3012C/LCD
7. Switch on the ~230V AC supply (red AC diode and green AUX diode should be lit).
8. Check the output voltage (the PSU voltage without load and without a battery should amount to 13,7 V ÷ 13,9 V,
with a battery or during battery charging process: 11,0 V÷13,8 V). If the value of the voltage requires adjustment, it
should be set by the VADJ potentiometer, monitoring the voltage at the AUX output of the PSU.
9. Connect the batteries in accordance with the markings: +BAT red to 'plus', -BAT black to 'minus’. The LB diode
should be on during battery charging process.
10. With the STOP button, activate or deactivate a dynamic battery test. Deactivating the test turns out the PSU
failure indication at the APS FLT output, but it does not affect the protection system against complete battery
discharge.
11. Check the current consumption of the receivers allowing of the battery charging current no to exceed the total
current efficiency of the PSU.
12. Once the tests and operation control have been completed, the enclosure can be locked.
8. Operation and use.
8.1. Over voltage protection OVP at the PSU output.
In case of voltage exceeding 15.5V±0.5V at the regulator’s output, the system cuts off the power at the
outputs to protect the battery and the receivers from damage. The outputs will be battery-powered. The protection
system is indicated by illuminating of the OVP red LED on the pcb board, PSU FLT output status change opening
state, acoustie and appropriate message on the PSU front panel.
8.2 Overload of the PSU.
The PSU has been equipped with a LED OVL (overload) indicator light on the pcb. It informs about the
output overload status. If the nominal current of the PSU is exceeded, the indicator light will be lit and the
microprocessor will proceed to a specially implemented procedure. If the overload threatens the PSU’s power
grade, the control system will decide about a disconnection of the AUX output. Restart will occur after 1 minute.
8.3 Short circuit at the PSU output.
In the case of a short circuit at the AUX, BAT output (load 200% ÷ 250% of the PSU power) or a reverse
polarity connection, the FBAT fuse in the battery circuit becomes permanently damaged and the restoration of the
voltage at the BAT output requires replacement of the fuse.
8.4 Battery replacement.
The battery replacement of the LCD panel should be done when the PSU is supplied from mains or a battery. This
will prevent the time settings from erasing
CAUTION!
The removed batteries ought to be stored in a dedicated place. The poles should not be
reversed. The use of the batteries of a different kind is forbidden. Tampering with the battery
may lead to its explosion.
8.5. Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the
power supply network. The PSU does not require performing any specific maintenance measures. However, in
the case of significant dust level, clean its interior with compressed air. In the case of a fuse replacement, use a
replacement of the same parameters.
