What kind of power supply do I need for a LED light?
Another advantage to this style of power supply is that they are simple to use, just plug them into your existing 100-240VAC electrical outlet and hook them up to your single color LED Lights, or LED Light components using any of our barrel connector products.
How to choose a power supply for your LED strip project?
Most LED strips will have a mark showing 12V or 24V. Now, check if the voltage on the power supply specifications matches the LED strip. In this case, the power supply is also 12V, so we are good to go. Also confirm that the input voltage on the AC side matches your country’s voltage (120V for North America, etc).
How many Watts Does a 12V power supply supply?
Now, let’s check the power supply. We see that it has a rating of 36W, or 3A. Again, if we use the formula P = V x A, this checks out, because it is a 12V power supply. What this means is that this power supply is capable of supplying up to 36 Watts, or about 3.0 Amps.
How many Watts Does a LED strip need?
If the power draw exceeds the power supply capacity, however, then the power supply can experience abnormal operation and damage. Therefore, this power supply can be used to power any LED strip that draws between 0 Watts and 36 Watts.
Can a constant voltage power supply be used for LEDs?
If you don’t have a current limiting device, finding a driver is your first step; but if your LED product already has current under control, you can follow this post in finding a constant voltage power supply. A constant voltage power supply can be used to power LED lights that have resistors or constant current drivers already within the system.
What kind of power supply do Cree LEDs need?
Say we have six Cree LEDs running off of a Mean Well LDD-H driver. Each LED runs at about 3.1 volts. With six of these our total voltage in this series circuit would be 18.6VDC. Typically, low voltage drivers like the Mean Well LDD-H work better if you have a small cushion over the voltage they require.
