inject power

[Craig]

We recommend using a single power supply wherever possible. However when using several thousand pixels on a single controller multiple power supplies are often required (and common practice) to get sufficient power. Its generally best to use identical power supplies and connect the negatives together to provide a common ground, then use the positives to inject power. We recommend inline fuses are used on power injection lines etc as high ampage output from power supplies can burn through thin pixel wire quickly in the event of a short.
