Power connection method of LED light string

Power connection method of LED light string

Generally, the voltage of LED light string is 12V DC, so switching power supply is needed. The size of power supply depends on the power and connection length of LED light string. If you don't want each LED string to be controlled by a power supply, you can buy a high-power switching power supply as the main power supply, and then connect all the input power supplies of the LED string in parallel (if the wire size is not enough, it can be extended additionally), and the power supply is unified by the main switching power supply.

The advantage of this is that it can be centralized control, and the inconvenience is that it can not achieve the lighting effect and switch control of a single LED light string. The specific method can be measured by yourself. I use Zhongshan Greenman's LED series are connected by the method of total power plus parallel connection.
