4. Setup and Installation
Follow these steps for proper installation:
- Power Disconnection: Ensure the main power supply is switched off before beginning any installation work.
- Mounting: 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.
- Load Check: Verify that the total wattage of all connected LED devices does not exceed 30 watts.
- Secure Connections: Double-check all wiring connections to ensure they are tight and correctly insulated.
- Power On: Once all connections are secure and verified, restore power to the circuit.

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. Maintenance
The Goobay 30003 LED Transformer requires minimal maintenance.
- Cleaning: Disconnect power before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Inspection: Periodically check the wiring for any signs of damage or loose connections.
- Ventilation: Ensure that ventilation openings are not obstructed.
7. Troubleshooting
If you encounter issues with your transformer, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| LEDs do not light up | No power supply Incorrect wiring Faulty LED(s) Overload protection activated | 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. |
| LEDs flicker or dim | Loose connection Insufficient power (near max load) Faulty LED(s) | Check all wiring connections. Ensure total load is well within the 30W limit. Test individual LEDs. |
| Transformer makes buzzing noise | Loose components 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 | Poor ventilation 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.
