1.1. General description.
The buffer power-supply is used for uninterrupted supply of devices requiring stabilized voltage of 12V DC
(+/-15%). The power-supply provides voltage within the following range: U= 11.0V÷13.8V DC of total current
efficiency equal to 10A. In case of power voltage decay, prompt switching to battery supply occurs.
The power-supply has got a metal casing (RAL 9003 colour) with a space for 40Ah/12V battery. The casing
features a micro-switch indicating door (front) opening and separating from the wall.

2. Installation.
2.1 Requirements.
The buffer power-supply shall be mounted by the qualified installer having appropriate (required and
necessary for a given country) permissions and qualifications for connecting (operating) 230V AC installations and
low-voltage installations. The device shall be mounted in closed rooms, according to the environment class II, of
the normal air humidity (RH=90% max. without condensation) and the temperature within the range from -10°C to
+40°C. The power-supply shall operate in a vertical position so that free and convectional air flow through
ventilating holes of the casing is guaranteed.
Before installation, the balance of the power-supply load shall be performed. During the normal operation,
the sum of currents collected by receivers shall not exceed I=10A (P=138W max.), including the maximum battery
charging current Ibat.
As the power-supply is designed for a continuous operation and is not equipped with a power-switch,
therefore an appropriate overload protection in the power supply circuit shall be guaranteed. Moreover, the user
shall be informed about the method of isolation of the power supply from the power voltage (usually through
assignment and marking of an appropriate fuse in the fuse-box). The electrical system shall be made in
accordance with valid standards and regulations.
2.2 Installation procedure.
1. Before installation is started, the voltage in the 230V power-supply circuit shall be isolated.
2. The power-supply shall be mounted in a selected location and connection cords shall be lead.
3. The power cables (230 VAC) shall be connected to L-N terminals of the power supply. The earth conductor shall
be connected to the terminal marked by the earth symbol
. The connection shall be made by means of a threecore cable (with a yellow and green PE protection wire). The power cables shall be lead to appropriate terminals of
the connection board through bushing.
The circuit of the shock protection shall be performed with a particular care, i.e. the yellow and
green protection wire of the power cable shall be connected from one side to the terminal
marked by the symbol of
in the casing of the power-supply. Operation of the power-supply
without the properly made and fully operational circuit of the shock protection is
UNACCEPTABLE! It can result in failure of devices and electric shock.
4. Connect the conductors of the loads to the +AUX-, +AUX1-, +AUX2-, +AUX3- terminals of the terminal box on
the power-supply unit.
8
5. If necessary, connect the conductors from the equipment to the technical outputs:
- BS AC status indication (alarm panel, controller, signalling unit, LED diode, etc.)
- AW technical output of failure
- TAMPER signalization of power-supply unit opening or separating from foundation
6. Using the jumper ‘J1’, ‘J2’ determine maximal battery charging current, take into consideration battery
parameters (refer to tab.1 page 4).
7. Using the jumper ‘J’ determine whether the function of disconnecting the discharged battery U<10V (+/-5%) is to
be on or off. The battery protection is on if the jumper ‘J’ is removed.
8. Activate the 230V AC supply (the AC diode should be permanently illuminated, and AUX O1, O2, O3 diode
should be permanently illuminated).
9. Check the output voltage (the power-supply unit voltage without load should be anywhere between
13.6V÷13.9V, and during battery charging 11V÷13.8V). If the value of the voltage requires adjustment, the setting
should be made by means of the potentiometer P1, monitoring the voltage at the AUX output of the PSU.
10. Connect the battery in accordance with the indications: +BAT red to ‘plus’ , -BAT black to ‘minus’, (the LB red
diode should go on and the lighting intensity should reduce with the charging time elapsed increasing).
11. Once the tests and control operation have been completed, lock the enclosure, cabinet, etc.
3. The power supply operation indication.
3.1 Optical indication.
The PSU is equipped with two diodes on the front panel:
RED DIODE:
• lights – the power-supply unit supplied with 230VAC
• does not light – no 230VAC supply
GREEN DIODE
• lights – DC voltage at the AUX output of the power-supply unit
• does not light – no DC voltage at the AUX output of the
power-supply unit
Moreover, the PSU is equipped with three diodes indicating operation status: AC, LB, AUX, O1, O2, O3,
and UVP, placed on the PCB of the power-supply unit module:
• AC - red diode: under normal status (AC supply) the diode is permanently illuminated. The absence of AC
supply is indicated by the AC diode going off.
• LB - red diode: indicates the battery charging process; the intensity of illumination is dependent on the
charging current.
• AUX - green diode: indicates the DC supply status at the output of the PSU. Under normal status, the
diode is permanently illuminated and in the case of short-circuits or overload, the diode goes off.
• O1, O2, O3 - green diodes: indicate the status of DC power supply at AUX1, AUX2, AUX3 outputs, which
are independently protected with 2.5A polymer safety equipment. In normal state, the diode emits
continuous light – in the case of short-circuit or overload, the diode goes off.
• UVP (fig.2) – red diode: signals the activation of the UVP overvoltage protection. In normal state, the
diode is off – in the case of short-circuit or overload, the diode emits continuous light.
3.2 Technical outputs.
The PSU is equipped with indication outputs:
•
BS - absence of AC supply output: - OC output type indicates the loss of AC supply in a normal status,
with the supply equal to 230V, the output is deactivated and in case of power supply loss the PSU
activates the output after 30s.
AW - technical output of failure: OC output type indicates failure the occurrence of at least one of the
following failures: SCP, OLP, UVP, voltage converter failure.
In normal state (correct operation), the output has the L status "ground" (0V) – in the case of failure, the
output is open (hi-Z high impedance).
•
•
TAMPER - output indicates opening the power-supply unit: output as volt-free contacts which indicate
power-supply unit door status and fastening to the ground: NC unit opened and/or wrongly fastened (e.g.
unit unconnected with the ground): NO.

4. Service and operation.
4.1 Overload of short-circuit to the power-supply output.
The output circuit has an electronic current protection. If permissible value of the Imax output current is
exceeded, the power-supply unit output voltage is disconnected and this is indicated by the O1, O2, O3 and AUX
diodes going off. The voltage is restored automatically, when the receivers are disconnected from the output.
Additionally, the AUX1, AUX2, AUX3 outputs of the power-supply unit are independently protected, using
the PTC polymer fuses. If the output is loaded with the current that exceeds 2.5A, the output voltage is
automatically disconnected, which is indicated by the O1, O2 or O3 green diode going off. The restoration of the
voltage at the output requires the disconnecting output load for the period of at least one minute.
In the case of the short-circuit to the AUX, BAT output, (load 200% ÷ 250% of the PSU power) or incorrect
connection of the battery, the fuse F1 in the battery circuit becomes permanently damaged. The restoration of the
voltage at the BAT output requires the replacement of the fuse.
4.2 Battery operation.
In the case of power failure, in the unit will instantly switch to the battery assisted operation.
In order to activate the operation of the PSU from the battery itself, connect the BAT connectors in accordance with
the indications: +BAT red to ‘plus’ and, -BAT black to 'minus’ of the battery and press and keep depressed for five
seconds the START pushbutton on the equipment board.
The PSU is equipped with the discharged battery disconnection system (UPV); the configuration of
functions through the jumper ‘J’. The battery protection is on if the jumper ‘J’ is removed.
4.3 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 rate, its interior is recommended to be cleaned with compressed air. In the case of fuse
replacement, only the substitutes in conformity to the original ones are allowed.
