12V 10A Switching Power Supply 120W

A switching power supply is an efficient electronic device designed to convert high-voltage alternating current (AC), typically 110V or 220V. This delivers 12V at 10 amps, totaling 120 watts. It is used where more current is needed, such as for multiple CCTV cameras, LED matrix displays, electric door locks, or mini DC motors. The switching technology allows the supply to be compact and efficient, preventing overheating and ensuring consistent performance.
