POWER SUPPLY UNIT TUL132
Installation Manual
FUNCTIONAL FEATURES
The power supply unit is composed by a linear feeder, with function of limitation of constant current
and an analogic control circuit.
The power supply is divided into 2 terminal outputs protected by the relative fuses:
- BAT : where buffer battery will be connected
- OUT 1 : for generic loads
Battery is charged with constant current ( 13,8 V @ 25°C).
Maximum current supplied by power supply is 2 A (1,5 A for load and 0,5 A for battery).
LED in control card (see picture n. 1) indicate:
- Current supplied by power supply over 2 A ( DL2 )
- Tension presence ( RETE )
To avoid that an eventual failure on the regulator, could damage loads or battery, a protection circuit
made by a SRC and a fuse against over voltage has been inserted.There is also a fuse for
alternating power supply.
In case of a fault in the power supply, or tension absence, the battery will provide power to logic and
check circuits

SECURITY INSTRUCTIONS
1. Utilize different fairlead holes on the bottom of the box, to pass cables for tension input and dc
output + alarms. Moreover, materials for pipe/box fitting must have HB inflammability class or
better.
2. “GUASTO” and “RETE RIT” relay contacts, must be connected only to circuits working with
SELV tension.
3. For AC power supply, use a differential magneto-thermic bipolar protection switch, easily
accessible.
4. Conductors must have cross section suitable to tension and equipped with adequate cable
terminals on contact pressure points.
5. Installation of unit must be executed by qualified personnel who know security requirements
EN60950 and concerning power supply units CEI 64-8.
INSTALLATION
Mechanical mounting
This unit has to be installed on vertical solid walls able to support the power supply unit using 4 plugs
of 6 mm, 4 washers and screws coming out from the 4 holes on the bottom of the box.
Electrical connection
Connect unit to power 230 Vac through a differential magneto-termic bipolar switch to protect line
against short circuit and operator from current leakage.
IMPORTANT: Utilize separated fairlead and tubes for input ac power supply ( 230 Vac) and dc
outputs + alarms (SELV).
Output terminals (Power supply)
BAT + Battery positive pole
BAT - Battery negative pole
OUT 1 + Positive output to load 1
OUT 1 - Negative output to load 1
ALTERNING POWER SUPPLY TERMINALS
Lline connection ( 230 Vac) land protection connection Nneutral connection
Check and adjustments
P1 e P2 check are calibrated from factory and must not be modified by operators. Tampering of
these checks will cause guarantee loss.
FRONT PANEL SIGNALS
- Low Battery:-check tension lower than 11 Vdc
- Battery OK: - tension between 11 Vdc and 14,5 Vdc
- Overloaded Battery: - tension higher than 14,5 Vdc
- Power Supply: - line tension 230 Vac
- Failure: - General failure pilot lamp: light up in case of:
Low battery –Overloaded battery –Tension absence 230 Vac –
Fuse failure –Disconnected battery –Battery charge loss
Fuses
F1 Input fuse power supply 230 Vac ( T 1 AL)
F2 Fuse for over tension protection ( T 3,15 AL)
F3 Battery fuse ( T 3,15 AL)
F4 Relative output fuse OUT 1 (T 2 AL)

Control circuit connection (placed behind frontal panel)
See Pict. 2
“Tension absence” Relay – Terminals 10 –11 –12 (working with SELV tension)
Output relay for tension absence with programmable delays of activation:
Jumper on JP1 to get a 15 seconds delay
Jumper on J1 to get a 15 minutes delay
Jumper on J2 to get a 60 minutes delay
Jumper on J3 to get a 120 minutes delay
Jumper on J4 to get a 240 minutes delay
NOTE: Without any jumper connected, the “Tension absence“ relay will be never activated.
“Failure signaling” relays – Terminals 4 –5 –6 (working with SELV tension)
Output relay for failure signaling, activated in case of:
Low Battery (tension lower than 11 Vdc)
Overloaded Battery (tension higher than 14,5 Vdc)
MAINTENANCE
In order to avoid power supply unit malfunctions, periodic and preventive maintenance must be
executed by qualified staff. Maintenance is recommended each 6 months. During all check
operations, there is the possibility of alarms, so coordination with control central is suggested.
- Check connection status of power supply line 230 Vac.
- Check connection status of alarm lines and relative screening.
- Check connections to battery. They must be not oxidized and well fastened.
- Check output tension on load (see Electrical Specifications)
