1. Technical description.
1.1 General description.
A buffer PSU is intended for an uninterrupted supply to devices requiring stabilized voltage of
12V DC (+/-15%). The PSU provides voltage of U=13,8V DC. Current efficiency:
1. Output current 6A + 1A battery charge*
2. Output current 5A + 2A battery charge*
Total device current + battery: 7A max*.
In case of power decay, a battery back-up is activated immediately. The PSU is constructed based on the
switch mode PSU, with high energy efficiency. The PSU is housed in a metal enclosure (colour RAL 9003) which
can accommodate a 17Ah/12V battery. A micro switch indicates door opening (front cover).

2. Installation.
2.1 Requirements.
The buffer PSU shall be mounted by a qualified installer with appropriate permissions and qualifications for
230V/AC installations and low-voltage installations (required and necessary for a given country). The device shall be
mounted in confined spaces, according to the environment class II, with normal air humidity (RH=90% max. without
condensation) and the 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.
Before installation, prepare a PSU load balance.
1. Output current 6A + 1A battery charge*
2. Output current 5A + 2A battery charge*
Total device current + battery: 7A max*.

RED LED:
on –the PSU is supplied with 230V AC
off –no 230V AC supply
GREEN LED:
on –DC voltage in the AUX output of the PSU
off –no DC voltage in the AUX output of the PSU
on –PSU’s voltage UBAT > 11,5V
off –PSU’s voltage UBAT < 11,5V
As the PSU 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 (usually through 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 (~230V AC) to L-N clips of the PSU. Connect the ground wire to the clip marked by the
earth symbol PE (PSU module connector). Use a three-core cable (with a yellow and green PE protection wire) to make
the connection. Lead the cables to the appropriate clips through the insulating bushing of the connection board.
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
‘‘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.
4. Connect the receivers’ cables to the terminals V+ (+), V-(-) of the PSU module.
5. Connect the power (~230V)
6. Connect the battery (mind the colours):
- battery output (+V): BAT+ cable / red,
- battery output (0V): BAT –cable / GND / black.
7. Check the PSU operation indicator: green LED.
8. Check the PSU output voltage:
- the PSU voltage without load should amount to U=13,8V DC.
9. After installing and checking proper working, the enclosure can be closed.
3. Operating status indication.
3.1 LED indication of operating status.
The PSU is equipped with 3 diodes on the front panel:
Moreover, the PSU is equipped with 3LEDs on the PCB board:
- red LED (Fig.2, element 1) normal status (AC power): permanently illuminated. AC power absence is
indicated by the AC diode going out.
Caution! LED indicates power absence if the outage lasts >10s.
- green LED (Fig.2, element 2) indicates DC power at the PSU output. Under normal status the diode is
permanently illuminated. In case of a short circuit or an overload, the diode is off.
- green LED (Fig.2, element 3) indicates battery voltage level. Under normal status (UBAT > 11,5V) the diode is
permanently illuminated. In case of decrease of battery voltage (UBAT < 11,5V) the diode is off.

3.2 Technical outputs
The PSU has indication outputs:
EPS - absence of AC supply output:
- OC type output that indicates AC power loss. Under normal status, with 230V AC supply, the output is
connected to ground (L level –0V). In case of power loss, the PSU will switch the output into high
impedance state hi-Z after approx. 10s.
- relay output indicating the absence of AC supply. In case of power loss, the PSU module will switch the relay
contacts after approx. 10 seconds.
CAUTION! In Fig.2. the contact set in the potential-free status corresponds to a state with no AC
power (AC power failure).
PSU –technical output indicating absence of DC voltage at the PSU:
- OC type output indicating the PSU failure. In normal state (during correct operation) the output is connected
to ground (L level –0V). In case of absence of DC voltage at the output (e.g. short circuit), the output is
switched into high impedance state –hi-Z.
- relay output. In case of a failure, the contacts of the relay change over.
CAUTION! In the Fig.2. the set of contacts shows a potential-free status of the relay which
corresponds to a state with no DC power (PSU failure).
LoB –technical output indicating battery voltage:
- OC type output. Under normal status (UBAT > 11,5V) the output is connected to ground (L level –0V). In case
of decrease of battery voltage (UBAT < 11,5V) the output is switched into high impedance state –hi-Z.
-relay output. In case of a battery voltage drop UBAT < 11,5V, the contacts of the relay change over.
The power supply unit does not feature a battery detection function. In the case of no battery or non battery
connected, the output is in the normal mode.
CAUTION! In the Fig.2. the set of contacts shows a potential-free status of the relay which
corresponds to a state with low battery level (UBAT <11,5V).

4. Operation and use.
4.1 Overload or short circuit of the PSU output (SCP on)
In case of overload, the output voltage is automatically shut off, and so is the LED indicator. The restoration
of the voltage takes place immediately after the failure (overload) is over.
4.2 Battery-assisted operation.
In case of a main power outage, the device is immediately switched into a battery-assisted operation.
The PSU is equipped with the discharged battery disconnection system. During the
battery-assisted operation, reducing voltage below 9,5V at the battery terminals will cause
battery disconnection.
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
case of significant dust rate, its interior is recommended to be cleaned with compressed air. In case of fuse
replacement, use a replacement of the same parameters.

WEEE MARK
According to the EU WEE Directive –It is required not to dispose of electric or
electronic waste as unsorted municipal waste and to collect such WEEE separately.
The power supply unit is adapted for a sealed lead-acid battery (SLA). After the operation period it must not be disposed of but recycled
according to the applicable law.
