Description
The AC220 Universal Adjustable DC 3V-24V 3A Adapter is a versatile regulated power supply designed for powering a wide range of DC electronic devices. It accepts a 100-240V AC input and provides an adjustable 3V to 24V DC output, allowing you to select the voltage required by your device.
The adapter features a compact PC+ABS engineering plastic housing and a convenient adjustable voltage control. With an output rating of up to 3A and 24W maximum power, it can be used for many low-voltage electronics, LED lighting, networking equipment, cameras, motors, and other compatible applications.
Important: The original product information contains conflicting current/power descriptions, including “1A” and “3A.” The detailed specification lists 3000mA output current and 24W output power, which is the specification used here.
