  • What cross-section must the cables have?
  • Do I need a fuse? Which one?
  • What are the power injections? Do I need them and how many?

    A longer LED strip with many LEDs can require quite a lot of power. In this case the current cannot be fed in full only at the beginning of an LED strip. The problem is that because of the voltage drop within the strip, too little voltage arrives at the rear LEDs, so that they don't shine with full intensity or the colors are even distorted. It may therefore be necessary to supply LED strips with power from back side or even additionally at one or more points in between. How many injections you need can be calculated with the WLED Calculator.

  • Does a 10 A fuse, for example, protect against currents greater than 10 A?
  • How do I select a fuse?
