HOW TO CALCULATE A POWER SUPPLY …?

Step 1 – Check if the input of your strip is 12V

Step 2 – Check how many watts per meter your LED strip will consume

Step 4 – Calculate the estimated power usage

 -Total length of led strip of 30 led/m used for progect is 10m :  10m x 7.2w = 72w

Step 5 – Understand the rule of 80%

 -When choosing a power unit, it’s a good idea to make sure you are only using 80% of the rated power maximum to increase longevity          of the power supply and keep it cool to prevent overheating:  72w / 0.8 = 90w

Step 6 –  Put it all together to determine the amps of power supply you need

 -Amps = Power / Volt       90W / 12V = 7.5 A
