4. Setup è Installazione
Segui questi passi per una stallazione curretta:
- Disconnection d'energia: Ensure the main power supply is switched off before beginning any installation work.
- Muntamentu: Select a suitable location for the transformer, ensuring it is dry, well-ventilated, and within the specified operating temperature range. The flat design allows for space-saving installation, including within furniture.
- Input Connection (PRI): Connect the AC mains supply (200-240V~, 50/60 Hz) to the input terminals labeled 'N' (Neutral) and 'L' (Live) on the transformer. Use appropriate wiring and ensure secure connections.
- Output Connection (SEC): Connect your 12V DC LED lighting system to the output terminals labeled '+' and '-' on the transformer. Ensure correct polarity (+ to + and - to -) for your LED devices. The transformer provides a constant 12V DC output suitable for parallel circuits.
- Verificazione di carica: Verificate chì u wat tutaletage of all connected LED devices does not exceed 30 watts.
- Cunnessioni sicure: Double-check all wiring connections to ensure they are tight and correctly insulated.
- Power On: Una volta chì tutte e cunnessione sò sicure è verificate, ristabilisce l'alimentazione à u circuitu.

5. Operating Instructions
The Goobay 30003 LED Transformer operates automatically once correctly installed and powered. It provides a stable 12V DC output for your connected LED devices.
- Ensure the total load of connected LEDs does not exceed 30W.
- The transformer is designed for continuous operation within its specified parameters.
6. Mantenimentu
The Goobay 30003 LED Transformer requires minimal maintenance.
- Pulizia: Scollegate l'alimentazione prima di pulisce. Aduprate un pannu asciuttu è dolce per asciugà l'esternu. Ùn aduprate micca detergenti liquidi o solventi.
- Ispezione: Periodically check the wiring for any signs of damage or loose connections.
- Ventilazione: Assicuratevi chì l'aperture di ventilazione ùn sianu micca ostruite.
7. Risoluzione di prublemi
If you encounter issues with your transformer, refer to the following table:
| Prublemu | Causa Possibile | Soluzione |
|---|---|---|
| I LED ùn si illuminanu micca | Nisuna alimentazione elettrica Cablaggio incorrettu Faulty LED(s) A prutezzione di sovraccarichi attivata | Check mains power and circuit breaker. Verify input and output connections and polarity. Pruvate i LED cù una fonte d'alimentazione cunnisciuta chì funziona. Reduce the total load; disconnect power, wait a few minutes, then reconnect. |
| I LED sfarfallanu o si affievoliscenu | Cunnessione libera Insufficient power (near max load) Faulty LED(s) | Verificate tutte e cunnessioni di cablaggio. Ensure total load is well within the 30W limit. Test individual LEDs. |
| Transformer makes buzzing noise | Cumpunenti sciolti Incompatible LED load (rare for constant voltage) Overload | Ensure secure mounting. If noise persists and performance is affected, discontinue use. Verify total load is within specifications. |
| Transformer is hot | Pobre ventilazione Overload | Ensure adequate airflow around the unit. Do not cover. Reduce the total load of connected LEDs. |
If the problem persists after following these steps, disconnect the power and contact customer support or a qualified electrician.
