1.1. General description.
HPSDC series stabilized power supplies are designed to supply power to HD cameras or other devices requiring
stabilized voltage of 12 V DC. Output voltage is adjusted with a potentiometer within the range of 12 - 15 V DC. The PSU
features 4, 8 or 16 outputs (depending on the model), protected independently by glass fuses.
A failure (an overload, a short circuit) in the output circuit will result in blowing of the fuse Fn and disconnection of the
corresponding AUXn output from the power supply. The power supplies are equipped with short-circuit, overload,
overvoltage and overcurrent protection. They are mounted inside a metal enclosure equipped with a signalling panel and
a microswitch indicating the opening of the door (lid).

2. Installation.
2.1. Requirements.
PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required for a
given country) for 230 V in and low-voltage installations. Unit should be mounted in confined spaces, in accordance, with
normal relative humidity (RH=90% maximum, without condensing) 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.
As power supply is designed for a continuous operation and is not equipped with a power-switch, therefore, an
appropriate overload protection in power supply circuit should be provided. 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.

LED green AC:
on –PSU is supplied with 230 V
off –no 230 V power
LED red FPS:
off –no failure
on –indicates fuse failure
2.2. Installation procedure.
CAUTION!
Before installation, cut off voltage in 230 V power-supply circuit. To switch power off, use an
external switch, in which distance between contacts of all poles in disconnection state is not less
than 3mm.
It is required to install an installation switch with a nominal current of min. 6 A in the power supply circuits
outside the power supply unit.
1. Mount the PSU in a selected location and connect the wires.
2. Connect power cables (~230 V AC) to L-N clips of PSU. Connect ground wire to clip marked by earth symbol .
Use a three-core cable (with a yellow and green protection wire ). Lead the power cables to the relevant terminals of
the power supply via an isolation conduit.
Shock protection circuit shall be done with a particular care: yellow and green wire coat of power
cable should be connected to terminal marked with the grounding symbol on PSU enclosure.
Operation of PSU without the properly made and fully operational shock protection circuit is
UNACCEPTABLE! It can cause damage to equipment or an electric shock.
3. Switch on 230 V supply. The LEDs on the PCB and on the lid of PSU should light up (see Section 3.1).
4. Check output voltage and adjust if necessary using potentiometer.
5. Disconnect the PSU from the mains and make the rest of the connections - connect wires to the AUX1...AUXn
connectors. If necessary, connect the wires from devices (control panel, controller, siren, etc.) to the PSU technical
outputs FPS (fuse failure indication output).
6. Once the tests and control operation have been completed, close the enclosure.
3. Operating status indication.
The power supply unit features LED status indication:
3.1 Optical indication.
The power supply unit features LED status indication. Presence of voltage at each output of the PSU is indicated
by the green LED nearby each outputs fuse. Failure (fuse damage) is indicated by shutting down green LED nearby
appropriate outputs fuse on the PSU module and illuminating the red LED FPS. Status of the PSU (fuse damage
AUX1 ÷ AUXn) can be remotely controlled via the FPS technical output.
In addition, there is an additional indication on the lid of the power supply:
4. Technical output.
The PSU features a relay type output indicating FPS fuse failure.
Caution! In Fig. 4 set of contacts shows a potential-free status of relay, which corresponds to power supply failure.

5. Operation and use.
5.1. Overload or short circuit of the PSU module output.
The AUX1÷AUXn PSU outputs are protected against short circuit by glass fuses. Activation of the protection (glass fuse
blowing) is indicated by shutting down green LED nearby appropriate outputs fuse on the PSU module and illuminating the red
LED FPS. In case of damage, replace the fuse (compatible with the original). As a precaution, it is possible to use fuses with a
higher current (up to 2 A) and a fast blow characteristic (F), which will increase the current-carrying capacity of the given output.
However, this does not affect the overall current capacity of the power supply.
5.2. Operation of the PSU OVP system.
If the OVP system is activated, the output voltage is automatically cut off. Operation can be resumed after
disconnecting the PSU from 230 V after approx. 1 minute.
6. 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 the case of
significant dust rate, its interior is recommended to be cleaned with compressed air.
