12V 3A 36W Metallic Switching Power Supplies
12V 3A 36W Metallic Switching Power Supplies AlphaTronics by Alpha Elettronica represents a reliable and robust solution for those looking for a versatile power supply with a resistant metal body. This power supply is designed to offer effective protection against overloads and short circuits, ensuring safety and durability over time. Its ability to be easily connected via screw terminals makes it ideal for powering a wide range of devices such as LED strips, routers, hubs, security cameras and audio-video systems.
The specific recommendation of having a power supply with a rating of 20% higher than the actual wattage of the device it is connected to, ensures that there is always enough power without overloading the system. For example, for a 10W per meter LED strip, you need a power supply of at least 12W to ensure efficiency and reliability.
