How to select appropriate transformer for 12V LED Strips

How to select appropriate transformer for 12V LED Strips

 

Step 1:  Calculate the power consumption of the strip you want

–We can calculate each strip’s power by knowing the LED Type and its rated power for each LED. The formula to calculate is Power Consumption = Wattage of each LED*LED QTY of strip Length.    

For example, for 100cm long SMD3528, 150LED/roll model, it’s 30LED per 100cm, so its power consumption is 30*0.08= 2.4Watt.
