LED Power Supply Calculator
How it works: the calculator multiplies the number of modules by the watts per module, adds the spare capacity you choose, and splits the modules into runs using the manufacturer's maximum per run. Wire each run back to the power supply separately, and for large signs use two or more supplies. Need help with a sign? Call 01892 783 900.

Pick your LED module and how many you're using. The calculator adds up the watts, allows spare capacity and tells you how many runs you need.
Module figures are from the manufacturer's datasheets. Allowing about 20% spare is a starting point; always follow the power supply manufacturer's instructions and check voltage drop on long runs. Need help? Call 01892 783 900.
