الوصف
An AC/DC power supply with a 12V 2A rating and a barrel jack converts wall power (AC) into direct current (DC) for electronic devices, featuring a universal AC input (100-240V), a 12-volt DC output, a maximum current of 2 amperes (24W), and a standard 5.5mm x 2.1mm center-positive barrel connector. Key features include built-in safety protections like over-voltage, over-current, and short-circuit protection, a regulated output for stable power delivery, and wide compatibility with devices like LED strips, CCTV cameras, and routers.
