The wiring method for the LED switching power supply is as follows:
Connecting to AC Power:
Connect the L and N lines to a 220V AC power source. This usually means you need to connect them to a household outlet.
The ground wire after the N line is optional for indoor use, but for safety reasons, it is recommended to connect it if possible.
Connecting the LED Strip:
The GND terminal needs to be connected to the negative terminal of your LED strip. The negative wire is usually black or white.
The 12V terminal needs to be connected to the positive terminal of your LED strip. The positive wire is usually red or brown.
Power-on Test:
After connecting the wires, test the power. If the LED does not light up, try swapping the GND and 12V wires.
If it still doesn't light up after swapping, possible causes include: a damaged LED strip, a power supply failure, or an open circuit.
Precautions: Before wiring, ensure the power is off to prevent electric shock. When wiring, be sure to connect the positive and negative terminals correctly according to the color correspondence to avoid reversing the connections and damaging the device. If you are unsure how to proceed, it is recommended to seek help from a professional.
