Q: How do I adjust the output voltage?

A: Use the built-in potentiometer (small screwdriver adjustment) accessible through the enclosure. Typical range: ±10% of nominal voltage (e.g., 10.8-13.2V for 12V model).

Q: Can I connect multiple LED strips?

A: Yes. For the 12V/29A model, you can power up to 350W of 12V LED strips. Always use appropriate gauge wire and distribute load across multiple terminals if connecting many strips.

Q: Is the fan always running?

A: The fan is temperature-controlled. It runs at low speed under light loads and increases speed as load/temperature rises. At very light loads (< 20%), the fan may not run at all.

Q: Can it be used outdoors?

A: This is an indoor-rated supply (IP20). For outdoor use, install it in a weatherproof enclosure with adequate ventilation.
