®APS-30
POWER SUPPLY
aps30_en 01/09
The APS-30 power supply is designed for alarm, intercom or CCTV systems. The power
supply proposed by our company has been designed and manufactured for such purposes.
Precision voltage regulation, microprocessor-based battery testing and automatic battery
disconnection in case of excessive discharging – all these features ensure that a battery can
be used for a longer period, without a risk of battery damage. Moreover the circuit of power
supply has a fuse of 3,15 A capacity. The power supply has short-circuit and overload
protection. It is provided with visual signaling of mains supply and battery conditions as well
as battery charging process. The detected failures can be additionally indicated by audible
signaling. Two additional OC outputs permit transferring information about failures to alarm
system. Due to the use of switching mode power supply of high power efficiency, heat power
losses are minimized, thus increasing reliability. The power supply should operate with
a 12 V battery of 17 Ah capacity.

1 – buzzer. Indicates troubles.
2 – POWER LED (red). Indicates presence of alternating voltage on the AC terminals.
3 – BATTERY LED (green). Indicates presence of battery.
4 – CHARGING LED (yellow). The LED is on during battery charging or state-of-charge
testing.
5 – battery connecting leads (red +; black -).
6 – pins for setting operating parameters of power supply unit. Symbol on the
electronics board means that the jumper is on. Symbol means that the jumper is off.
BEEPER – switching the beeper on/off.
AC FAIL DELAY – sets the time that must elapse after AC power supply failure until the
failure is indicated on the AWS output (0, 60, 600 or 1800 seconds).
BATT. CHARGE – sets the battery charging current: 0.5 A or 1 A.
BATT. CHECK – switches the battery test on/off.
Description of terminals:
AC – power supply input (17...24 V AC). The AC terminals are used for connection
the secondary winding of mains transformer.
COM – common ground.
+12V – outputs of power supply unit (13.6 – 13.8 V DC).
AWS – output indicating failure of 230 V power supply.
AWB – output indicating low battery or battery failure.
1. Installation
Before starting an installation, a balance of power supply loads should be made. Under
normal service conditions, the sum of the load currents plus the battery charging current
can not exceed the power supply capacity (of 3 A).
The power supply should only operate while being permanently connected to mains supply.
Hence, before making the connections it is necessary to familiarize with the electric system in
the facility. For powering the device choose the circuit which is always live. The power supply
circuit should be protected with a proper fuse.
Before connecting the device to its power supply circuit, make sure that the
supply circuit is not alive.
1. Mount four distance plugs in the power supply back panel according to the spacing of the
board openings. Plugs under the pressure can not slip out from installation spaces.
2. Mount the power supply enclosure in the selected location and lead all connecting wiring.
3. Connect 230 V AC power wiring to the 230 V AC transformer terminals, and the grounding
wire to the terminal situated on the back of the metal housing and marked by the ground
symbol .
4. Mount the board with electronics on the distance plugs, and, using screws, secure the
board with LEDs to the housing cover (descriptions of LED indicators - see Legend to
Fig. 1).
5. Using the installed cables, connect the transformer output voltage (rated at 20 V AC) to the
AC terminals on the electronics board.
6. Connect the wiring from the loads to the terminals +12 V and COM at the terminal strip on
the power supply board.

7. If necessary, connect the wiring from the alarm control panel to AWS output (output for
signalling 230 V AC power loss) and (or) to AWB output (output for signalling battery low
voltage or battery failure). During normal operation of the power supply unit, the signaling
output is shorted to the ground (0 V), but when any of the above mentioned causes
occurs, it becomes cut off from the ground.
Figure 2. Schematic view of AWS and AWB outputs.
8. Using jumpers, set the time delay on the AC FAIL DELAY pins after which 230 V AC
power failure shall be signaled. Possible time delay settings:
0 seconds – Pins open
60 seconds – Pins shorted
600 seconds –
1800 seconds –
9. Using the BEEPER pins, determine, whether the beeper is to be switched on (jumper
on), or not (jumper off).
10. Using the BATT. CHARGE pins, determine the battery charging current (jumper on
- 0.5 A; jumper off – 1 A)
11. Switch on 230 V AC mains supply (if all connections are properly made, LEDs marked as
POWER and BATTERY should be ON).
12. After connecting the power supply, it is possible to measure the voltage across battery
cables. The correct voltage should be approx. 13.7 V.
13. Connect the battery according to the colour marking. If the battery is discharged, green
LED (BATTERY) will start flashing after approx. 4 minutes from switching on 230 V AC
mains supply. In case that the battery is connected after this period (green LED is
already flashing), the battery charging conditions shall be known after performing the
next test by the power supply – after approx. 12 minutes. Charging the battery is
signalled by a steady light of yellow LED, its brightness depends on charging current.
The second function of the yellow LED is signalling the test procedure for checking the
battery voltage. Every 4 minutes this diode is ON for several seconds, during which the
processor reduces the power supply voltage and the loads are powered from the battery.
The battery test function can be disabled by removing the jumper BATT. CHECK.
Disabling the test will also deactivate the battery failure signaling on the AWB output,
without, however, switching off the circuit which protects the battery from complete
discharge.
14. Next, the proper operation of failure monitoring circuits can be checked (with the BATT.
CHECK jumper set on):
Switch off AC power – the red LED (POWER) shall start flashing and the failure of AC
power shall be acoustically signalled by the power supply. After the time delay, set on the
pins, the status of AWS output shall change. When AC power is restored, LED will light
permanently, audible signaling shall be switched off and AWS output shall stop signalling
the AC power failure after the time delay set on the pins.

Disconnect the battery – after approx. 12 minutes the green LED (BATTERY) will start
blinking and the power supply will generate audible signaling. The failure status shall
appear at AWB output. The reconnection of the battery will result, after approx.
12 minutes, in ending the failure indication by LED and beeper.
After installing and checking the proper operation of the power supply, its housing can be
closed.
As the power supply has no isolating switch to disconnect the mains supply, it is
important to inform the user or the owner of this device about the way of
disconnecting it from the mains (e.g. by indicating the fuse which protects the
supply circuit).
