1. Technical description
1.1 General description
The power supply unit is intended for the feeding of alarm system equipments, which require
12V DC. Their design enables simple changing of the output voltage, within the range of 12V÷15V DC, using a
potentiometer. The power supply unit is protected against short-circuit, overload and overvoltage.

2. Installation.
2.1 Requirements
The 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 positi on that
guarantees sufficient convectional air-flow through ventilating holes of the enclosure.
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 (most frequently through separating and assigning an appropriate fuse in
the fuse-box). The electrical system shall follow valid standards and regulations.
The device should be installed in the metallic enclosure, distribution board (ICT cabinet) equipped with a
DIN TH35 rail (35 mm wide). In order to meet the UE requirements, the rules concerning: supply, development and
shielding ought to be followed- accordingly to the application.
2.2 Installation procedure
1. Install an enclosure, a distribution board or a cabinet and lead the cables through the cable ducts.
2. Install the PSU on the DIN rail: Mount the PSU onto the rail and block with a clip (Fig. 3)
3. Connect the receivers’ cables to the OUTPUT (+,-) terminals of the terminal block on the PSU module’s board.
4. Connect the 230VAC power leads (L, N).
5. Activate the ~230V/AC supply (the DC OK diode green should be permanently illuminated)

6. Check the output voltage PSU. If the value of the voltage requires adjustment, it should be set by the V
adj
potentiometer (12 ÷15V DC), monitoring the voltage at the output of the PSU.
7. Once the tests and operation control have been completed, the enclosure/cabinet can be locked.
Rys.3. Mounting on a DIN rail.
3. Operation and use.
3.1 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.
3.2 Maintenance
Any and all maintenance operations may be performed following the disconnection of the PSU module from
the power supply network. The PSU module 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.
