2. Description of the power supply
Explanations for Fig. 1:
wires connecting the electronics board and the LED board.
LED board.
red LED indicating the AC mains power supply status:
ON – AC power OK,
flashing – no AC power.
green LED indicating the battery status:
ON – battery OK (or the battery status control disabled),
flashing – low battery (battery voltage below 11 V).
yellow LED indicating the battery charging process. It is on when the battery is being charged
(brightness of light depends on current consumption). When the battery status control is
enabled, the LED goes on for a few seconds every 4 minutes to indicate the battery check.
sounder for trouble indication.

pins for configuring the power supply operating parameters. The symbol on PCB indicates
that the jumper is placed across the pins, and the symbol – that the jumper is removed
from the pins.
BEEPER – enable / disable the audible trouble signaling (jumper ON – enabled,
jumper OFF – disabled).
AC FAIL DELAY – define the time that must elapse from the moment AC failure occurs
before the AWS output is activated. Set the delay time according to the
markings on the electronics board. Permissible times are indicated in
Table 1.
BATT. CHARGE – select battery charging current (jumper ON – 0.5 A, jumper OFF –
1 A).
BATT. CHECK – enable / disable the battery status control (jumper ON – enabled,
jumper OFF – disabled). Disabling the battery status control turns off
the battery trouble signaling on the AWA output.

Description of terminals:
AC – power input (17-24 V AC).
COM – common ground.
+12V – power supply output (
13.6-13.8 V DC) .
AWS – OC type output indicating loss of 230 V AC power.
AWB – OC type output indicating low voltage or failure of the battery.
In the normal state, the OC type output is shorted to common ground (0 V). In the active state
(trouble signaling), the output is disconnected from common ground.
3. Installation
Disconnect power before making any electrical connections.
Before installation, prepare a load balance so as not to overload the power supply.
In normal operating conditions, the sum of currents consumed by the connected
devices and the battery charging current must not exceed 3 A.
The power supply has been designed for use with lead-acid batteries or other
batteries having similar charging characteristics. Using other batteries than the
recommended ones may cause an explosion.
The used batteries must not be discarded, but should be disposed of in accordance
with the existing rules for environment protection.
The transformer should be permanently connected to the 230 V AC mains supply. Before you
make the cabling, familiarize yourself with the electrical installation of the facility. Make sure that
the circuit you choose for powering will be always alive. The circuit should be protected with
a proper safety device. The owner or user of the power supply should be instructed on how to
disconnect the transformer from the mains (e.g. by indicating the fuse which protects the supply
circuit).
A 12 V lead-acid sealed battery can be connected to the power supply as a backup power
source. The power supply enclosure can accommodate a battery with 17 Ah capacity.
If the power supply is to be installed in another enclosure (e.g. SATEL made OPU-3 P or
OPU-4 P), skip the steps from 1 to 7 and mount the electronics board as recommended in
the installation guide for the given enclosure.
1. Insert 4 spacers in the corresponding holes in the enclosure base. The spacers must not
come out of the holes when under pressure.
2. Run the cables through the hole in the enclosure base.
3. Use 4 screws to secure the enclosure base to the mounting surface.
4. Turn off power supply in the 230 V AC circuit to which the transformer is to be connected.
5. Connect the 230 V AC cables to the terminals of transformer primary winding. Connect the
ground cable to the terminal on the back panel of the enclosure.
6. Break off the separate LED board from the electronics board.
7. Mount the electronics board on the spacers and secure the LED board with screws to the
enclosure cover. Make sure the LEDs enter their corresponding holes according to the
designations on the enclosure cover:
– red LED (AC supply),
– green LED (battery status),
– yellow LED (battery charging).

8. Connect the terminals of transformer secondary winding to the power supply AC terminals.
9. Connect the devices cables to the terminals +12 V and COM.
10. You can connect LEDs, relays etc. to the trouble signaling outputs or connect these outputs
with the alarm control panel zones.
11. Using jumpers, set the power supply operating parameters.
12. Connect the battery to the dedicated leads (positive terminal to RED lead, negative terminal
to BLACK lead).
13. Turn on 230 V AC power supply in the circuit to which the transformer is connected. The
power supply unit will start (LEDs will come on).
4. Battery status control
The battery status is checked every 4 minutes and indicated by lighting up of the yellow LED .
If the battery voltage drops below 11 V for longer than 12 minutes (3 battery tests), the power
supply will signal a battery trouble. The AWB output will be disconnected from the common
ground, and the green LED will start blinking (optionally, the trouble can be audibly signaled).
The voltage drop to about 9.5 V will disconnect the battery.
