Chart 1.
Acceptable output current of the PSU is 4x1A with
the preset 12V voltage at the output. If this voltage
exceeds 12V, the receiverscurrent consumption
shall be reduced, according to the chart 1.
In case of a power loss, a battery back-up is activated immediately. The PSU is mounted in a metal
enclosure (RAL 9003 colour) that accommodates 2x7Ah/12V batteries and a microswitch indicates door opening
(faceplate). The enclosure design enables mounting 4-channel video module featuring proper connection outlets
for the Yap leads (coax cable).

2. Installation.
2.1 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 2nd 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
position that guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
1. Output current 4 x 1A + 0,2A battery charge
2. Output current 4 x 1A + 0,5A battery charge
Total current of the receivers + battery: 4,5A max.
Acceptable output voltage of the PSU amounts to 4x1A with the 12V voltage set at the output. If the voltage value
AT the output is higher than 12V, limit the receivers’ current consumption according to chart1.
As the PSU module 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.
2.2 Installation procedure.
1. Before installation, cut off the voltage in the 230V power-supply circuit.
2. Mount the PSU in a selected location and connect the wires.
3. Connect the power cables (~230Vac) to L-N clips of the PSU. Connect the ground wire to the terminal marked by
the earth symbol – “ ” on the plate. Use a three-core cable (with a yellow and green PE protection wire) to make
the connection. Lead the cables to the appropriate terminals of the connection board through the 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 ‘
earth symbol in the PSU enclosure. Operation of the power supply without a properly made
and fully operational shock protection circuit is UNACCEPTABLE! It can result in device
damage or an electric shock.
4. Connect the receivers’ cables to the +AUX, -AUX connectors of the terminal block on the PSU board.
5. If necessary, connect the devices’ wires to the technical outputs:
- FAC; AC status indication (alarm panel, controller, indicator, LED, etc.)
- FPS; technical output of the PSU operating status.
- FBL; technical output of the battery operating status.
6. Allowing of the battery parameters, determine the maximum charging current using the I
BAT
jumper.

7. With the OVP1 ÷ OVP4 jumpers, choose the over voltage protection, separately for each channel. The protection
level must be set min. 1,5V higher than the output voltage.
8. Supply the ~230V/AC to the transformer (the AC red diode and AUX diode should be permanently illuminated).
9. With the V
ADJ
potentiometer, set the required output voltage value, separately for each channel, monitoring the
voltage at the AUX output of the power supply.
10. Connect the batteries in series, in accordance with the markings: +BAT red to 'plus', -BAT black to 'minus’.
11. Check the PS operating status indication: green LEDs at the AUX1 ÷ AUX4 outputs.
12. Once the tests and operation control have been completed, the enclosure can be locked.
3. Operating status indication.
3.1 LED indication
The PSU is equipped with 8 LEDs in the front panel:
RED LED:
on – the PSU is supplied with 230V AC voltage
off – no 230V AC power
RED LED:
on – low battery voltage V
BAT
<23V
off – correct battery voltage
RED LED:
on – PSU failure
off – no failure
YELLOW LED:
on – battery charging process
off – no battery charge
GREEN LED:
on – DC voltage at the AUX1… AUX4 output
off – no DC power at the AUX1… AUX4 output
Additionally, the PSU is equipped with LEDs inside the enclosure – Fig. 2 and 3.
3.2 Technical outputs.
The PSU has some indication outputs:
FAC – technical output indicating absence of AC power:
- OC type output that indicates loss of the AC supply. Under normal status - with the 230V supply, the AC
output is fault to ground (status L – 0V). In case of power loss, the PSU output is switched into high
impedance state –hi-Z after a time period set by the J1 and J2 jumpers: 5s/140s/17m/2h20m.
- R – relay type output that indicates loss of the AC supply. In case of the power loss, the power supply unit
will switch the relay’s contacts after a time period set by the J1 and J2 jumpers: 5s/140s/17m/2h20m.
CAUTION! In Fig. 2 the contact set show a potential-free status of the relay. That corresponds to a
state with no AC power (AC power loss).
FPS – technical output of the PSU operation status: - OC type output indicating the PSU failure (a short
circuit, an overload). Under normal status (during correct operation) the output is connected to ground (L
level – 0V). In case of a failure, the output is switched into high impedance state – hi-Z.
FLB – technical output of the battery low level: - OC type output indicating low level of the battery
during battery-assisted operation. For battery voltage of V
BAT
>23V the output is connected to ground (L – 0V
level). If the battery voltage drops below V
BAT
<23V, the output will be switched into high impedance state - hi-
Z.
The technical outputs are implemented in an OC - open collector system shown in the following diagram:
www.pulsar.pl PSBSEP04124

Fig. 5. Electrical diagram of the OC technical outputs.
TAMPER - output that indicates unwanted opening of the PSU: contains volt-free (potential-free)
contacts indicating the door status - unit closed: contacts normally closed (NC), unit opened: contacts
normally open (NO)
4. Operation and use.
4.1 Procedure in case of a short circuit at the PSU output
The AUX1 ÷ AUX4 PSU output is protected against a short circuit by fuses or polyswitches (the selection is
made by the FS-x jumper). If the fuse-assisted protection has been chosen, replace the fuse (of the same
parameters) after a failure. If the polyswitch-assisted protection has been chosen, there will be an automatic
disconnection of the output voltage indicated by the green diode going out. Then, cut off the load from the PSU
output for approx. 1 minute.
4.2. Procedure in case of a short circuit at the BAT output or battery reverse polarity connection
In case of a short circuit at the BAT output or a battery reverse polarity connection, the F
BAT
fuse in the battery
circuit becomes permanently damaged. To restore the voltage at the BAT output, replace the fuse.
4.3 Procedure in case of activating the PSU OVP system
The PSU is protected against over voltage at the AUX1 ÷ AUX4 outputs. The over voltage protection threshold
is selected by the OVP-x jumpers. When the OVP system is activated, the output voltage is automatically cut off.
This is indicated by the AUX green diode going out and illumination of the appropriate OVPx diode. Restoring the
correct operation is possible after lowering the output voltage with a potentiometer or by increasing the protection
threshold.
The level of protection is to be set min. 1,5V higher than the output voltage.
4.4. Battery-assisted operation
In case of the main power outage, the device is immediately switched into a battery-assisted operation.
In order to run the PSU from the battery only, connect the BAT connectors in accordance with the signs: + BAT red
to ‘plus’ and, - BAT black to 'minus’ then press the START button on the main board and hold it for 5 seconds.
The PSU module is equipped with the discharged battery disconnection system (UVP),
configured by the P
BAT
jumper. The protection mode is off when the P
BAT
jumper is removed.
4.5. 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
case of dust, clean the interior with compressed air. Periodically, the condition of the batteries should be checked.
In case of faults (e.g. capacity loss, too high internal resistance), the batteries should be exchanged to new ones.
In case of fuse replacement, use a replacement of the same parameters.
