The 12V 1.5A 24W AC-DC Switching Power Supply Adapter is widely used for Wi-Fi routers, CCTV cameras, LED strip lights, LED lighting systems, DVRs, set-top boxes, Arduino projects, ESP32 development boards, Raspberry Pi accessories, IoT devices, embedded systems, communication equipment, mini audio amplifiers, security systems, biometric devices, electronic instruments, portable testing equipment, battery charging applications, home automation systems, educational electronics, and DIY electronics projects.

Whether you are replacing an existing power adapter, powering a development board, or supplying stable DC power to electronic equipment, this adapter provides reliable performance, high efficiency, and long service life.

Working Principle

The 12V 1.5A Switching Power Supply Adapter converts 100–240V AC mains power into a regulated 12V DC output using high-frequency switching technology.

The incoming AC voltage is first rectified and filtered into high-voltage DC. This voltage is then switched at a high frequency through a compact transformer, stepped down to the required level, and rectified again to produce a smooth and stable DC output.

A built-in feedback control circuit continuously monitors the output voltage and automatically adjusts the switching process to maintain a constant 12V DC output, even when the input voltage or connected load varies. Integrated protection circuits ensure safe operation under abnormal electrical conditions.
