How to install LED strip and power supply

LED strip, also known as led tape light, is one of the most popular linear decorative lighting fixtures for homes, shops, supermarkets, hotels, etc. Due to most of the LED strips' input voltage is 12V DC or 24V DC, they can't be directly connected to the 110V AC or 220V AC. So we need a power supply to transfer the high voltage AC to low voltage DC. Now let's see how to install LED strip and power supply.

Please note that the power must be cut off before installation to avoid the risk of electric shock.

1. Power supply wiring

Here is a typical power supply which inputs 100V to 220V AC and outputs 12V DC. As you can see from the picture below, the first and second interfaces are the high voltage input, and the third interface is the ground electrode. The first step is to connect the power cord to the input ends and tighten them with the screwdriver.

 2. LED strip wiring
In general, the red wire is the anode of the LED strip and the black wire is the cathode, which should be connected to V+ and V- of the output ends of power supply accordingly. The colors of the wires of the LED strip may be different from the different models or suppliers.
