Product Details This 3V-12V 2A adjustable AC DC power adapter provides flexible DC power for electronic equipment with different low-voltage power requirements. The adjustable output range allows users to select a suitable voltage for compatible devices instead of using a separate fixed-voltage adapter for each application.The universal power supply format makes it suitable for a wide range of electronics, including routers, CCTV equipment, LED devices, development projects and other low-voltage electronic products. Its external adapter design provides a convenient way to supply DC power without integrating the AC to DC conversion circuit into the end equipment.With a maximum output current of 2A, this adjustable power adapter can support various small electronic systems and equipment. It can also be considered for OEM applications where a configurable external AC DC power solution is required.
