1. Technical description.

1.1. General description.

The buffer power supply is designed to supply cameras or other devices requiring stabilized voltage of 12V

DC (+/-15%). The PSU features 4 independently adjustable channels for power supply in the range of

4x12÷18VDC/4x1A. This enables compensation of voltage drops in complex CCTV systems. The current efficiency

of the PSU is:

1. Output current 4 x 1A + 0,2A battery charging

2. Output current 4 x 1A + 0,5A battery charging

Total current of the receivers + battery is max. 4,5A.

Diagram 1.

The maximum output current is set to 4x1A at the

output voltage of 12V. If the output voltage is higher

than 12V, reduce the power consumption by the

receivers according to the diagram 1.

In case of mains power loss, the unit will instantly switch to battery operation. The PSU is enclosed in a metal

casing (color: RAL 9003) with battery housing for two 7Ah/12V batteries. The enclosure is fitted with a microswitch

indicating door opening (at the front). The enclosure of the PSU design allows mounting 4-channel MSEP412 or

MSEP412V video module, fitted with Yap cable connection sockets (coaxial cable integrated with the power

supply).

2. Installation.

2.1. Requirements.

The buffer PSU should be mounted by a qualified installer, holding relevant permits and licenses

(applicable and required for a given country) for 230V/AC 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, no condensation) and temperature range from -10°C up to +40°C. The power supply should

operate in a vertical position in order to provide free and convectional air flow through ventilating holes of the

enclosure.

1. Output current 4 x 1A + 0,2A battery charging

2. Output current 4 x 1A + 0,5A battery charging

Total current of the receivers+ battery is max. 4,5A.

The maximum output current is set to 4x1A at the output voltage of 12V. If the output voltage is higher than 12V,

reduce the power consumption by the receivers according to the diagram (page 3).

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 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.

2.2. Installation procedure.

1. Before installation, make sure that the voltage in the 230V power-supply circuit is cut off.

2. Mount the PSU in a selected location and lead the connecting cables.

3. Connect the power cables (230V AC) to L-N terminals of the PSU. Connect the ground wire to the terminal

marked with grounding symbol: . Use a three-core cable (with a yellow and green PE protection wire) to make

the connection. The power cables should be connected to the appropriate terminals on the connection board

through the bushing

The shock protection circuit shall be done with a particular care: the yellow and green wire

coat of the power cable should be connected to the terminal marked with the symbol

on the PSU enclosure. Operation of the PSU without the properly made and fully operational

shock protection circuit is UNACCEPTABLE! It can cause damage to the equipment or an

electric shock.

PSBSEP04124 www.pulsar.pl

- FAC; AC status indication (alarm panel, controller, indicator, LED etc.).

- FPS; technical output of the PSU operation status.

- FBL; technical output of the battery status (page 9 – technical outputs)

6. Use the FS-1 ÷ F4-1 jumpers to select overvoltage protection, protecting individual circuits against short circuit /

overload:

– melting fuse activation

–PTC fuse activation

7. Use the I

BAT

jumper to determine the maximum battery charging current, taking into account battery parameters

( I

BAT

jumper on: charging current 0,2A, I

BAT

jumper off: charging current 0,5A)

8. Switch on the ~230V AC power to the transformer (AC LED should be permanently illuminated, AUX LED should

be permanently illuminated).

9. Use the V

ADJ

potentiometer to set the required output voltage of individual circuits, monitoring the voltage at the

AUX output.

10. Use the OVP1 ÷ OVP4 jumpers to select to select the type of overvoltage protection of individual circuits. The

protection level should be set min. 1,5V above the output voltage.

11. Connect the batteries in series according to the markings: +BAT red to 'plus', -BAT black to 'minus’.

12. Check the optical indication of the PSU status: green LED lights at the AUX1 ÷ AUX4 outputs.

13. In case of mains power loss, it is possible to run the PSU from the battery. To do that, press and hold the

START button for 5 seconds (component 2, Fig. 2).

14. Close the cover after installing and checking the operation of the power supply.

3. Power supply operation indication.

3.1 Optical indication.

The PSU is fitted with 8 LED lights at the front panel:

RED LED:

 on – The PSU supplied with 230V AC voltage

 off – no 230V AC mains supply

RED LED:

 on – low battery voltage V

BAT

<23V

 off – battery voltage OK

RED LED:

 on – battery failure

 off – no failure

YELLOW LED:

 on – battery charging

 off – no battery charging

GREEN LED:

 on – DC voltage at the AUX1 ÷ AUX4 outputs

 off – no DC voltage at the AUX1 ÷ AUX4 outputs

Additionally, the PSU is fitted with LEDs on the PCB – see Fig. 2:

- AC red LED (Fig. 2, component 14) – is permanently illuminated during normal operation (AC power ON).

No AC power is indicated by turning off the LED.

- FPS red LED (Fig. 2, component 5) is not illuminated during normal operation (no failure). In case of activation of

the short circuit / overload protection at any output, the LED is permanently illuminated.

- AUX1 ÷ AUX4 green LEDs (Fig. 2, component 5) indicate voltage at the individual outputs of the module (L1 for

AUX 1 etc.). Activation of the short circuit / overload protection of a given circuit is indicated by turning off one of

the Lx LEDs.

- FLB red LED (Fig.2, component 5) – indicates battery voltage. During normal operation (UBAT > 23V), it is

permanently illuminated. In case of battery voltage drop (UBAT < 23V) the LED is off.

- LB yellow LED (Fig. 2, component 4) – indicates battery charging. The LED goes out at the end of the charging

process.

PSBSEP04124 www.pulsar.pl

3.2 Technical outputs.

The PSU has the following indication outputs:

 FAC – technical output indicating AC power failure

- OC type output indicating AC power failure. During normal operation, (230V AC power on) the output is

shorted to ground (L state – 0V). In case of power loss, the PSU will switch the output into hi-Z state (high

impedance) after a time lag set by the J1 and J2 jumpers: 5s/140s/17m/2h20m.

- R type output – relay type, indicating AC power failure. In case of failure, relay contacts are switched

automatically after a time lag set by the J1 and J2 jumpers: 5s/140s/17m/2h20m.

CAUTION! The arrangement of contacts at the figure 6 shows a potential-free status of the relay,

which is equivalent to AC power failure.

 FPS – technical output of the PSU operation status: - OC type output indicating failure (short-circuit,

overload). During normal operation, shorted to ground – L state (0V). In case of failure, the output is switched

into hi-Z state (high impedance).

 FLB – technical output indicating low battery voltage: - OC type output indicating low battery voltage

during battery operation. For the battery voltage V

BAT

>23V, the output is shorted to ground (L state – 0V). If

the battery voltage has dropped below V

BAT

<23V, the PSU will switch the output into high impedance state hi-

The technical outputs of the PSU are in the open collector (OC) configuration as shown in the Figure

below.

Fig. 5. Electrical diagram of the OC technical outputs.

Fig. 6. Electrical diagram of the relay output

 TAMPER - output indicating enclosure opening: - volt free contact input indicating the status of the

power supply doors, PSU closed: contacts closed (NC), PSU open: contacts open (NO).

4 Service and operation.

4.1 Procedure in case of short-circuit of the power supply output (SCP activation).

The AUX1 ÷ AUX4 outputs are protected against short-circuit by melting fuses or PTC polymer fuses

(protection type is adjusted with the FS-x jumper). In case of melting fuse activation, it should be replaced with a

fuse of the same type. If the PTC polymer fuses are used, the output voltage is automatically disconnected, which

is indicated by switching off the green LED. Disconnect the load from the power supply output for approximately 1

minute.

4.2 Procedure in case of short-circuit of the BAT output or reverse battery connection.

In case of short-circuit of the BAT output or reverse battery connection, the F

BAT

fuse in the battery circuit

becomes damaged. Restoration of the voltage at the BAT output requires fuse replacement.

4.3 Procedure in case of overvoltage protection OVP activation.

The PSU is protected against overvoltage at the AUX1 ÷ AUX4 outputs. Overvoltage protection thresholds are

selected with the OVP-x jumpers. In case of overvoltage protection activation, the output voltage is automatically

disconnected, which is indicated by switching off the green AUX LED and turning on the corresponding OVPx LED.

To resume operation, lower the output voltage with a potentiometer or shift the overvoltage protection threshold to

higher values.

The protection level should be set min. 1,5V above the output voltage.

www.pulsar.pl PSBSEP04124

4.4 Battery operation.

In case of mains power loss, the unit will instantly switch to battery operation. To run the PSU from the

battery, connect the BAT connectors in accordance with the markings: +BAT red to 'plus', -BAT black to 'minus’ on

the battery, then press and hold the START button for 5 seconds.

The power supply is equipped with deep discharge battery protection (UVP), configured

with the P

BAT

jumper.

The battery protection is on when the P

BAT

jumper is off

4.5 Maintenance.

All maintenance procedures can be performed after disconnecting the power supply from the power

network. The PSU does not require any specific maintenance; however, its interior should be cleaned with

compressed air if used in dusty conditions. The battery status should be checked periodically. In case of any

failures (battery capacity loss, too high internal resistance), the batteries should be replaced. In case of fuse

replacement, use only compatible replacement parts.
