12V3A 36W AC100V-240V Switching Power Supply Transformer

The 12V 3A Switching Power Supply converts standard AC electricity into a stable 12V DC output. It supports a wide 100V to 240V AC input range, making it suitable for many locations and power systems. This unit provides up to 3A of output current and a maximum power rating of 36W. It can power LED strips, CCTV cameras, small amplifiers, access control devices, electronic locks, and automation projects. It is also useful for Arduino projects, small DC motors, pumps, and other compatible 12V devices. The metal case helps protect the internal parts while allowing heat to escape. Open slots provide airflow during use and help reduce heat buildup. The built-in screw terminals make it easier to connect the AC input and 12V DC output wires. This power supply includes protection against overvoltage, overcurrent, and short circuits. These safety features help protect the unit and connected equipment during unexpected electrical problems. Install the power supply in a dry, clean, and well-ventilated area. Keep the terminals covered and away from water or conductive materials. Wiring should be completed by someone with proper electrical knowledge. Before connecting a device, check that it requires 12V DC and draws no more than 3A. For long-term use, avoid operating the power supply at its full 36W rating for extended periods.
