Many people buy LED lights with controllers, but they don't know how to use them. They are very confused. Now let me explain to you: using the LED light band controller requires two things, one is the power adapter, the other is the LED light band. As for the power adapter, it needs to be selected according to the V number of LED lamp belt and LED lamp belt controller. The V number of LED lamp strip and lamp strip controller is generally between 5-24v. LED light band and light band controller will also be marked. You need to select the power adapter according to the V number. There is also power. Generally, you need to choose a power supply of about 3a.

When everything is ready, you can start to use the LED lamp with the controller. Now connect one end of the power supply to the socket, and then connect the output line of the power supply to the DC base or input end of the controller. Then connect the output line of the controller with the light bar. Pay attention to the positive and negative poles of the light bar and connect it with the positive pole of the controller. Only in this way can the light band be lit and the controller not burn out.
