4. Configurazione e installazione
Per una corretta installazione, seguire questi passaggi:
- Disconnessione dell'alimentazione: Ensure the main power supply is switched off before beginning any installation work.
- Montaggio: 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.
- Controllo del carico: Verificare che il totale wattage of all connected LED devices does not exceed 30 watts.
- Connessioni sicure: Double-check all wiring connections to ensure they are tight and correctly insulated.
- Accensione: Una volta che tutti i collegamenti sono sicuri e verificati, ripristinare l'alimentazione al circuito.

5. Istruzioni per l'uso
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. Manutenzione
The Goobay 30003 LED Transformer requires minimal maintenance.
- Pulizia: Disconnect power before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Ispezione: Periodically check the wiring for any signs of damage or loose connections.
- Ventilazione: Assicurarsi che le aperture di ventilazione non siano ostruite.
7. Risoluzione Dei Problemi
If you encounter issues with your transformer, refer to the following table:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| I LED non si accendono | Nessuna alimentazione Cablaggio non corretto Faulty LED(s) Protezione da sovraccarico attivata | Check mains power and circuit breaker. Verify input and output connections and polarity. Test LEDs with a known working power source. Reduce the total load; disconnect power, wait a few minutes, then reconnect. |
| I LED tremolano o si attenuano | Collegamento allentato Insufficient power (near max load) Faulty LED(s) | Controllare tutti i collegamenti del cablaggio. Ensure total load is well within the 30W limit. Test individual LEDs. |
| Transformer makes buzzing noise | Componenti sciolti Incompatible LED load (rare for constant voltage) Sovraccarico | Ensure secure mounting. If noise persists and performance is affected, discontinue use. Verify total load is within specifications. |
| Transformer is hot | Scarsa ventilazione Sovraccarico | 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.
