ELECTRONIC TRASFORMER FOR LED LAMPS 12V
Type: LTC 5/23-LED
The digitally controlled electronic transformer use sensitive electronic components and should be handled with the same care as
any other electronic equipment. In order to achieve a long life and correct functioning, both in the electronic transformer and in
the LED lamps, it is necessary to follow these manufacturer's recommendations.

LED lamps that work correctly with the LTC 5/23-LED transformer
If two or more lamps are installed in the same transformer, the cables must be of the same length (maximum 1m.) So as not to
obtain different luminosity in each lamp due to the different voltage drops in the wiring.
Those wires situated near to the lamp must be made of material which can support high temperatures.
A good connection in the wires must be ensured in order to minimize the notable effects of the contact resistance in the
connections.

If an insulation test in the circuits which supply the electronic equipment in the installation is carried out, it must be done
applying the test voltage between the phases and the neutrals all together and the earth wire.
The test voltage must never be applied the phases and the neutral or between phases.

}
Wiring with the correct insulation, lengths and cross-sections must be used. For the same power, the current in a circuit is 20
times higher at 12V than at 230V.
Because of the voltage drop, the maximum length allowed in cables connected to the transformer's secondary is:

ELECTRIC SUPPLY
The voltage and frequency of the mains supply must be within the normal
operating range.
In 400V triphase installations, the neutral must always be connected, if it is
interrupted the 400V could reach the equipment and there would be a risk of
damage. When the installation is carried out the charge between the phases
must be as equally balanced as possible.

¡ Caution !
SAFETY
Avery low voltage installation (LVI) must be carried out whilst taking the necessary precautions in order to respect the safety of
all its parts. The contact or crossing between the mains supply conductors and the very low voltage installation conductors
must be avoided and the insulation between the conductors must be > 4kV.
Maintenance and the changing of parts must be carried out by a qualified person with the mains disconnected and the
instructions and cirrent regulations must be strictly followed.
TEMPERATURE
It must be ensured that the maximum atmospheric temperature in the installation does not exceed
the ta marked on the equipment, and an adequate degree of protection against humidity must be
ºC provided.
Under no circumstances must the tc temperature marked on the transformer’s casing be
exceeded due to the fact that continued operation at higher temperatures produces a progressive
reduction in life expectancy. The electronic transformer includes thermal protection which acts to
minimize the damage and faults in the equipment in these conditions.
