The AC-DC 12V 3A SMPS Power Adapter converts household mains power into a steady 12V DC supply with up to 36W of output for your electronics projects and 12V devices. Its switching design is compact, lightweight, and far more efficient than bulky linear adapters, so it runs cooler and wastes less power.
With a universal 100 to 240V AC input, it has the capacity to run higher-current 12V loads such as LED strips, CCTV cameras, DVRs, routers, mini UPS units, motor driver boards, and larger relay banks. The standard 5.5mm x 2.1mm barrel plug is centre positive and fits most DC jacks, so setup is quick and simple.
A reliable power source is the foundation of any project, and this adapter is a handy, budget-friendly choice for hobbyists, makers, and students building on the workbench or installing small systems. Always confirm that your device needs 12V DC with a centre positive plug and draws no more than 3A before connecting it.
