3. Technical description.
3.1 General description.
The buffer power supply is designed in accordance with the requirements of the EN 50131-6 standard,
grade 1÷3 and II environmental class. It is intended for an uninterrupted supply of alarm system devices requiring
stabilized voltage of 24VDC (+/-15%).
Depending on a required protection level of the alarm system in the installation place, the PSU efficiency
and the battery charging current should be set as follows:
* Grade 1, 2 - standby time 12h
Output current 0,58A + 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 – EN 50131-1 standard).
Output current 0,23A + 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 – EN 50131-1 standard).
Output current 0,116A + 1,5A battery charge
*** General use – if the PSU is not mounted in an installation complaint with the EN-50131 standard, the
acceptable current efficiency amounts to:
1. Output current 2A + 0,2A battery charge
2. Output current 1,6A + 0,6A battery charge
3. Output current 1,2A + 1A battery charge
4. Output current 0,7A + 1,5A battery charge
Total current of the receivers + battery: 2,2A max.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal
enclosure (color: RAL 9005 - black) with battery space for a 2x7Ah/12V battery. It is fitted with micro switches
indicating unwanted door opening (front panel) and detachment from the mounting surface.

4. Installation.
4.1 Requirements.
The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for 230V/AC in and low-voltage installations.
As the power supply is designed for a continuous operation and is not equipped with a powerswitch, therefore, an appropriate overload protection in the power supply circuit should be provided. Moreover, the
user should be informed how to disconnect the power supply unit from the mains supply (usually by assigning an
appropriate fuse in the fuse box). The electrical system shall be made in accordance with applicable standards
and regulations. The power supply should operate in a vertical position in order to provide free and
convectional air flow through ventilating holes of the casing.
4.2 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 particularly important 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
EN 50131-6 standard.
Fig. 4. 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 detachment from the assembly surface.
- EXT IN; input of collective failure.
5. With the IBAT jumper determine the maximum battery charging current, in accordance with the battery
parameters.
6. With the PBAT jumper determine if the discharged battery disconnection system U<20V (+/-5%) shall be on or off.
The battery protection is on when the PBAT jumper is off.
7. Switch on the ~230V AC supply (red AC diode and green AUX diode should be on).

BLACK POWER
8. Check the output voltage (the PSU voltage without load and without battery should amount to 27.5V ÷ 27.7V,
with a battery or during battery charging process: 22V÷27.6V). If the value of the voltage requires adjustment, it
should be set with use of 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. Press the STOP button to 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, taking into account the battery charging current, so as not to
exceed the total current efficiency of the PSU.
12. Once the tests are completed, close the PSU cover.

Then, after one second, the next failure code will be automatically displayed.
- if the memory has more failures, pressing the "OK" button will result
in displaying subsequent codes
- the „- - -„ parameter on the display marks the end of the list of failures
5.2.4 Current failures „FLc”
In case of abnormal electrical parameters, the power supply provides optical and acoustic indication of the
failure via corresponding LED and a beeper (if not disabled).
The PSU can simultaneously indicate several failures. Thanks to this solution, codes of all failures and their
priority can be previewed in the FLc menu. In the FLc menu, each press of the "OK" button on the panel displays
the next error code that caused the failure. If there are multiple failures at the same time, pressing the "OK" button
will display the next code. The display order of failures is arranged by priority of importance. The first failures in the
display order are of the highest priority.
Section 5.2.5 summarizes all the failure codes that may occur during the power supply operation. The
individual codes are accompanied by appropriate optical indication on the panel, acoustic indication and activation
of the dedicated technical output.

5.5 Technical outputs.
The PSU feature indication outputs, with galvanic isolation, which change their state if any of the following
events occur:

EPS FLT - output indicating AC power loss.
The output indicates 230V AC power loss. Under normal status (with 230V supply on) the


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 23V during battery-assisted operation
- battery fuse failure
- 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<23,6V
- high output voltage Uaux>29,4V
- high battery voltage Uaku>28V (during battery test)
- polymer fuse PTC activation
- exceeding the PSU nominal current
- failure in the battery charging circuit
- activation of the over voltage protection OVP
- enclosure opening - TAMPER
- internal damage of the PSU
- EXT IN input activation
The technical outputs have been implemented with galvanic isolation between the PSU’s systems and the
attached devices.
Fig. 8. Electrical diagram of the technical outputs.
5.6 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. The voltage at the EXT IN input will save information about an incident in
the internal memory of the power supply 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. 9. Electrical diagram of the EXT IN input.
22

BLACK POWER
The electrical diagram below shows the way of connecting external devices to the EXT IN input. Outputs
such as: OC (open collector), relay may be used as a source of the signal.
Fig. 10. Examples of connections.
In the option with tamper switches, the VEXT jumper must be on. It polarizes 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. 11. Example of a connection with the fuse module: AWZ535 or AWZ536.
5.7 Enclosure Tamper Indication - TAMPER.
The PSU is fitted with the micro switch tamper indicating enclosure opening and detaching from the
mounting surface.
The tamper cable is not connected to the terminal in the factory settings. In order to activate tamper,
remove the jumper from tamper terminal (Fig. 2 [14]) and plug in the tamper cable.
Each opening the enclosure and detaching from the mounting surface will generate a failure signal at the
PSU FLT and ALARM technical outputs and will save the event in the internal memory of the PSU.

5.8 Overvoltage protection of the PSU output OVP.
In case of voltage exceeding 31V±0.5V at the switching 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 activation of the protection system is indicated by the OVP yellow LED on the PCB board, and the PSU FLT
output.
5.9 PSU overload.
The PSU is fitted with the LED OVL (overload) on the PCB and
indicator on the LED panel,
informing about output overload. If the nominal current of the PSU is exceeded, the led turns on and the
microprocessor starts a specially implemented procedure. Depending on time and overload level,
microprocessor may disconnect the AUX output and switch into the battery-assisted operation. Restart will occur
after 1 minute.
PSU overload is indicated by the PSU FLT technical output.

6 Reserve power supply circuit.
The power supply is equipped with intelligent circuits: charging and battery control circuit, whose main task
is to monitor the condition of the battery and its connections in the circuit.
If the power supply driver detects a malfunction in the battery circuit, appropriate signaling and change in the
APS FLT technical output take place.
6.1 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.
6.2 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 20V±0.2V will turn on the beep sound and disconnect the battery in the 15
seconds.
Re-connecting the battery to the power supply occurs automatically upon the appearance of the 230V AC mains
voltage.
The protection mode is off when the PBAT jumper is removed.
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.
6.3 Battery test.
The PSU runs battery test every 5 minutes. During testing, the control unit of the PSU measures the
electrical parameters according to the implemented measuring method.
A negative result occurs when the battery circuit continuity is interrupted or if the terminal voltage drops
below 24V
The battery test can be activated manually (see section 5.3.1), from the menu of the power supply or by
pressing the STOP button, for example to test the replaced batteries.
The PSU is protected against too frequent performing of the battery test, which could result in
undercharging. The protection involves blocking the ability to perform test for 60 seconds from the last activation.
n such case, the LED will display the „- - -„ symbol.
Temporary lock of the battery test can be disabled by putting the J1 jumper between J2 on the power
supply board (Fig.2 [2]).
The battery test will also be automatically locked when the PSU is in the operating mode, in which the
battery test is impossible. Such condition occurs, for example, during battery assisted operation or when the power
supply is overloaded.

6.4 Standby time.
Battery-assisted operating depends on battery capacity, charging level and load current. To maintain an
appropriate standby time, current drawn from the PSU in battery mode should be limited. Characteristics for a
2x7Ah/12V SLA:
Grade 1, 2 - standby time 12h
Output current 0,58A + 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 – EN 50131-1).
Output current 0,23A + 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 – EN 50131-1).
Output current 0,116A + 1,5A battery charge
6.5 Battery charging time.
The PSU has a battery circuit charged with direct current. The current selection is done with use of the IBAT
jumpers. The table below shows how long does it take to charge a (fully discharged) battery up to min. 80% of its
nominal capacity.

6.6 Operation without a battery.
In case of an expected PSU operation without an attached battery, make a necessary configuration of the
jumpers:
In this mode, the automation system allows adjustments of PSU’s output voltage without indicating a failure
connected with battery operation.
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.

7. Remote monitoring (options: 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 responsible for communication in Wi-Fi, Ethernet or RS485 standard. The USB –TTL
interface enables the connection between the PSU and the computer.
Different connection topologies, presented later in this chapter, are only a part of possible communication
schemes. More examples can be found in the manuals dedicated to individual interfaces.
When installing optional features in the power supply unit, power supply current consumption, used
for the calculation of standby time, should be taken into account (see section. 6.4).
7.1 Communication via the USB-TTL interface.
The easiest way of communication between the PSU and the computer is provided by the USB-TTL "INTU”
interface. This interface allows direct connection between the computer and the PSU and is recognizable by the
operating system as a virtual COM port.
Fig. 12. USB-TTL communication using the USB-TTL „INTU” interface.
7.2 ETHERNET network communication.
Communication in the Ethernet network is possible due to the additional interfaces: Ethernet „INTE” and
RS485-ETH „INTRE”, according to the IEEE802.3 standard.
The Ethernet „INTE” interface features full galvanic isolation and protection against surges. It should be
mounted inside the enclosure of the PSU.
Fig. 13. Ethernet network communication using the Ethernet „INTE” interface.
27

PSBEN2024B
BLACK POWER
The RS485-WiFi „INTRE” interface is a device used to convert signals between the RS485 bus and the Wi-Fi
network. For proper operation, the unit requires an external power supply in the range of 10÷30V DC e.g. drawn
from a PSU of the PSBEN series. The unit is mounted in a hermetic enclosure protecting against adverse
environmental conditions.
Fig. 14. Ethernet network communication using the RS485 „INTRE” interface.
7.3 The Wi-Fi wireless communication.
The Wi-Fi wireless communication can be implemented on the basis of additional WI-Fi ‘INTW’
and RS485-WiFi interfaces, operating within 2,4GHz frequency band, according to the IEEE 802.11 bgn standard.
The Wi-Fi “INTW” interface shall be mounted in a selected location inside the enclosure so that the
antenna is exposed to the outside.

The RS485-WiFi „INTRW” interface is a device used to convert signals between the RS485 bus and the
Wi-Fi network. For proper operation, the unit requires an external power supply in the range of 10÷30V DC e.g.
drawn from a PSU of the PSBEN series. The physical connection of the interface takes place under galvanic
isolation. The unit is mounted in a hermetic enclosure protecting against adverse environmental conditions.
Fig. 16. The Wi-Fi communication using the RS485-WIFI „INTRW” interface.
7.4 RS485 network communication.
Another type of network communication is the RS485 communication using two-wire transmission path. To
achieve this kind of data exchange, the PSU should be equipped with the additional RS485 TTL "INTR" interface,
converting data from the PSU into the RS485 standard and the USB-RS485 "INTUR" interface, converting data
from the RS485 network to the USB. Offered interfaces are galvanically isolated and protected against surges.

7.5 „PowerSecurity” program.
The ”Power Security” program is available at www.pulsar.pl
Its detailed description can be found in the manual.
„Power Security” is a free computer program for viewing and analyzing the information sent from the PSU
installation spots. The main panel is presented below.
Fig. 18. „Power security” main panel.
It is possible to divide the main panel of the program into smaller areas, depending on the number of
monitored power supplies.
The program is equipped with manager mode, which allows the grouping of power supplies for easier
analysis and orientation.
The application enables both the visualization and analysis of the received data. Exceeding of the
acceptable parameters is indicated by red illumination of the appropriate area or by blinking of the indicator light.
Individual tabs allow monitoring the power supply parameters on the chart and failure memory along with the
information about the status of technical outputs and electrical parameters.
