How to Connect a LED Strip to a Power Supply

This guide walks you through connecting a single-color LED strip to a constant voltage power supply safely.

🔧 What You’ll Need​

  • LED strip (12V / 24V)
  • Matching PSU (e.g., 24V 100W)
  • Screwdriver or WAGO connectors
  • Optional: Dimmer (PWM or 0–10V)

📝 Steps​

  1. Check the strip voltage (printed on strip): e.g., 24V.

  2. Cut strip to length at marked cut points (e.g., every 50mm).

  3. Wire the PSU:

    • Brown = Live (L)
    • Blue = Neutral (N)
    • Green/yellow = Ground (⏚)

  4. Connect the LED strip:

      • (red) → V+
    • – (black/white) → V–

  5. Turn on the power and test.

⚠️ Always match voltage and add 20–30% headroom to your PSU.
