Max Connection quantity instruction of LED backlight strip:
Please note that LED backlight strip is dimmable:
Remarks:
1) As the carrying capacity of the connection line between light bar and LED strip is limited, maximum capacity of LED strip is 12 amps. One roll of light bar cannot be connected to another light bar roll during installation. Each roll requires a separate power supply. LED backlight strip will be controlled within the maximum quantity for per roll during production.
2) When the number of connections of a light curtain is more than the specified amount, the line loss of the wire is greatly attenuated, which leads to the decrease of the input voltage. Therefore, the connection loop is required to ensure the reliability of safe use. Overloading can lead to fire and accidents.
3) Depending on the number of connections, you need to calculate the power of each piece to match the proper power supply for the entire light box connected to the switching power supply, with a wire diameter in the middle of more than 2 square millimeters.
