As usual, our input of the COB LED Strip Light or SMD LED strip light is 12VDC or 24VDC. So we need to match a power supply or a transfer for them.
For example, you buy a roll of our 12VDC 480 pcs LEDs COB LED Strip Light 8mm,ILED-COB-480-8mm-12V, what power supply do you need to buy?
At first, you should check the watts of cob led strip light, our ILED-COB-480-8mm-12V is 8W / meter, one roll is 5 meters, so total power supply is 40W.
The input is 12VDC, and the main voltage is 220-240VAC.
So do we choose a power supply which has input 220-240VAC, output 12VDC, and the max load watts is 40W?
Answer: NO, we need buy a power supply with below paramter,
Input: 220-240VAC
Output: 12VDC
Max load watts: 40W*1.2 = 48W.
Why do we need to match 1.2 x the watts of strip light? Please see our coming article,
Why does the switching power supply only carry 80% of the load?
