AC 110-220V to DC 5V 4A 20W Switching Power Supply Driver Transformer for LED Strip Lights

This LED dedicated switching power driver supports global household AC voltage ranging from 110V to 220V, outputting steady 5V DC at 4A (total 20W power) to power all standard 5V LED light strips, cabinet lights and small light signage. Adopting optimized constant voltage circuit design, it effectively suppresses voltage ripple to keep LED brightness uniform without flickering, greatly extending the service life of your light strips. High conversion efficiency reduces power waste and surface heat even under long-hour lighting operation. The fully sealed plastic shell blocks dust and slight splashes, while internal intelligent protection chips automatically cut power under abnormal conditions to prevent damage to the power supply and LED lights.

Clear positive and negative terminal ports simplify wiring installation. Plug-and-play design works for home decoration, TV background lighting, display cabinet LED strips and commercial small light signs, an economical dedicated power transformer for all 5V low-voltage LED lighting projects.
