How to choose the right LED power supply for the light stripTime:2021-04-21 / Read:312
Confirm light strip voltage:
When purchasing the ligtht strip, we can know the voltage of the light strip through the parameters of the strip, and the strip will also have the mark of 12V or 24V.Then we can choose the LED power supply with the same voltage according to the voltage of the LED strip.
Confirm the power of the LED strip:
Similarly, when we buy a light strip, we can know the power of the LED strip from its parameters.
Usually we do not distribute power when we buy LED lamp strips, so after calculating the required length of LED strips, we need to calculate the power required for the power supply, so as to buy the matching power supply;The following is a common LED strip with power:
0603LED light strip :12V, 60 pieces per meter, power per meter 1.5W
1210LED light strip :12V, 60 pieces per meter, power per meter 4.8W
3528LED light strip :12V, 60 pieces per meter, power per meter 4.8W
5050LED light strip :12V, 30 pieces per meter, power per meter 7.2W
5050LED light strip :12V, 60 pieces per meter, power per meter 14.4W
If the LED strip is 1210 and the power supply model is 12V 5A, how should I calculate the required length of the LED strip?
We can use the formula to calculate: Power Supply (P) = Power Supply (V) * Power Amperes (A) 12*5=60W,60W/4.8W=12.5m. In general,we do not recommend full load power supply, otherwise it will affect the power supply service life, it is recommended to use 85% load, 12.5*0.85=10.625m, so we can conclude that the use of 60W power supply can match the 1210 LED light strip of 10 meters.
In addition, there are 5V or 24V light strip. Customers only need to choose the appropriate power supply according to the model parameters of the light strips and through the above calculation formula.
