A 12V 3A power supply converts AC mains power into a stable 12-volt DC output, delivering up to 36 watts of power. It is ideal for powering medium-power electronics such as LED strips, CCTV cameras, routers, development boards, and small appliances. Designed for reliable operation, it provides consistent voltage, low ripple, and built-in protection against overload and short circuits.
