1. Technical description.
1.1. General description.
The buffer power supply is intended for uninterrupted supply of CCTV systems requiring stabilized
voltage of 12V DC (+/-15%). The PSU supplies voltage of 13,8V DC and total current capacity of:
1. Output current 4x1A + 1A battery charging
2. Output current 4x1A + 2A battery charging
Total current of the receivers + battery is max. 6A.
The PSU is constructed on the basis of the switch mode PSU. The PSU is characterized by high energy
efficiency and is housed in a metal enclosure (color RAL 9003) with battery housing for one 7Ah/12V battery. The
power supply unit enables transmitting power and video using a 75 ohm coaxial cable integrated with two power
wires (YAP type). Additionally, it is equipped with BNC sockets for connecting the video signal. The power supply
outputs are independently protected by melting fuses or PTC polymer fuses. Failure (short circuit) in the output
circuit will activate the melting fuse or PTC fuse and disconnect the circuit from DC power (+ U). Fuse failure is
indicated by switching off the corresponding LEDs: L1 for AUX1, etc. In addition, the FPS output (hi-Z state) and
LFPS LED are activated and the relay contacts change their position. The PSU is housed in a metal enclosure with
signaling panel equipped with a microswitch indicating door opening (front cover).

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 sh ould
operate in a vertical position in order to provide free and convectional air flow through ventilating holes of the
enclosure.
The power supply load balance should be done before installation:
1. Output current 4x1A + 1A battery charging
2. Output current 4x1A + 2A battery charging
Total current of the receivers + battery is max. 6A.
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, cut off the voltage in the 230V power-supply circuit.
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
in 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.
4. Connect the power supply line and video signal to the BNC module (See Figure 4):
- connect the supply voltage of the camera to the AUX1÷ AUX 4 outputs

www.pulsar.pl BNC04124B GREEN POWER CCTV BNC

- connect the video signals from the cameras and the DVR to the BNC sockets
Figure 4. Connecting the camera and DVR to the BNC module.
5. Use the F1/PTC1 ÷ F4/PTC4 jumpers to select the type of short circuit / overload protection of individual circuits.
Jumper in the Fx position – melting fuse activation, PTCx – PTC fuse activation.
6. If needed, the following technical connections can be made:
- FPS technical output of the PSU status – indicates the voltage loss at any of the outputs (AUX1 ÷ AUX4).
- TAMPER indicating enclosure opening.
7. Check the power supply output voltage:
- output voltage of the unloaded power supply without a battery should amount to U=13,8V DC.
8. Set the battery charging current using the jumper (component 4, Figure 5):
Figure 5. Selection jumper for charging current.
Selection jumper for charging current:
Ibat =1 A Ibat =2 A
Description: jumper on, jumper off.
Factory setting: Ibat =1A (jumper on).
9. Connect the battery according to the color markings:
- battery output (+V): BAT+ cable / red
- battery output (0V): BAT- cable/ black
10. Check the optical indication of the PSU status: green LED light on the BNC module.
11. Close the cover after installing and checking the operation of the power supply.
3. Power supply operation indication.
3.1.Optical indication.
The PSU has 11 LED lights at the front panel:

www.pulsar.pl BNC04124B GREEN POWER CCTV BNC
8
RED LED:
•on – The PSU supplied with 230V AC voltage
•off – no 230V AC mains supply
RED LED:
•on – DC voltage at the output of the switch mode PSU
•off – no DC voltage at the output of the switch mode PSU
RED LED:
•on – fuse failure at one of the AUX1…AUX4 outputs
•off – no failure
GREEN LED:
•on – DC voltage at the AUX1…AUX4 output
•off – no DC voltage at the AUX1…AUX4 output
Additionally, the PSU is fitted with LED lights inside the enclosure – see Figure 2 and 3:
- L
AC
red LED (Figure 2, component 1) is permanently illuminated during normal operation (AC power ON).
No AC power is indicated by turning off the L
AC
LED.
- L
IN
green LED (Figure 2, component 1) indicates DC voltage at the BNC module input. During normal operation
(DC supply) the LED is permanently illuminated. No DC no DC voltage at the module input is indicated by turning
off the L
IN
LED.
- L
FPS
red LED (Figure 2, component 10) 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.
- L1 ÷ L4 green LEDs (Figure 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.
3.2.Technical outputs.
The PSU has the following indication outputs:
•FPS – technical output of the PSU status:
- OC type output indicating failure (short-circuit, overload). During normal operation, shorted to ground – L
state (0V). In case of power loss, the FPS technical output is switched into hi-Z state (high impedance) at least
at one of the AUX outputs.
Figure 6. Electrical diagram of the OC output.
- relay output. In case of failure, relay contacts are switched automatically.
Figure 7. Electrical diagram of the relay output
CAUTION! The arrangement of contacts at the figure 7 shows a potential-free status of the relay,
which is equivalent to a state with no voltage at any of the AUX1 ÷ AUX4 outputs.

•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.Overload or short-circuit of the power supply output.
The AUX1÷ AUX4 outputs of the PSU are protected against short-circuit by
melting fuse inserts or PTC
fuses. In case of melting fuse replacement, use only compatible replacement parts. If the PTC polymer fuses are
used, then automatic disconnection of the output voltage, indicated by switching off the green LED, takes place. In
such case, disconnect the load from the power supply output for approximately 1 minute.
4.2. Battery operation
In case of mains power loss, the unit will instantly switch to battery operation.
The power supply is equipped with a discharged battery disconnection system. If
the voltage at the battery terminals has dropped below 9.5V during battery operation, the
batteries will be disconnected.
4.2.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. In case of fuse replacement, use only compatible replacement parts.
