4. Postavljanje i instalacija
Slijedite ove korake za pravilnu instalaciju:
- Isključivanje struje: Ensure the main power supply is switched off before beginning any installation work.
- Montaža: 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.
- Provjera opterećenja: Provjerite da li je ukupna vattage of all connected LED devices does not exceed 30 watts.
- Sigurne veze: Double-check all wiring connections to ensure they are tight and correctly insulated.
- Uključeno: Nakon što su svi priključci sigurni i provjereni, vratite napajanje u strujno kolo.

7. Otkrivanje problema
If you encounter issues with your transformer, refer to the following table:
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| LED diode ne svijetle | Nema napajanja Neispravno ožičenje Faulty LED(s) Aktivirana zaštita od preopterećenja | Provjerite glavno napajanje i osigurač. 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. |
| LED diode trepere ili se prigušuju | Slaba veza Insufficient power (near max load) Faulty LED(s) | Provjerite sve veze ožičenja. Ensure total load is well within the 30W limit. Test individual LEDs. |
| Transformer makes buzzing noise | Labave komponente Incompatible LED load (rare for constant voltage) Preopterećenje | Ensure secure mounting. If noise persists and performance is affected, discontinue use. Verify total load is within specifications. |
| Transformer is hot | Loša ventilacija Preopterećenje | 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.
