The latest company news, industry developments and knowledge
about LED light strips and LED grow lights are Shared here.
Most LED strips work at 12V or 24V DC, but in most countries, the standard voltage is 110V or 220V AC, so we need a power supply (adaptor) to convert standard high-voltage AC into a low-voltage DC that can be used by LED strips. In this post, we are going to introduce how to connect the LED strip light to the power supply and lit it up.
Note: Please cut off the power before installation to avoid the risk of electric shock.
Step 1: Power supply installation
The interfaces of the power supply are divided into input interfaces and output interfaces. According to the icons on the power supply, we connect L and N to high voltage AC and the third is the ground mark.
Step 2: LED strip installation
Connect the red wire of the LED light strip to the positive pole V+ of the power supply output, and connect the black wire to the negative pole V-. Power on.
The installation of RGB LED strip
RGB multi-color LED strip lights need to achieve color change through the controller. So we need to install a controller between the power supply and the LED strip to control the input current of the light strip.
