AC Adapter 5V 3A Wall Mount | DC Jack 2.1mm

When powering electronics and Arduino Board projects, it’s always important to use a power supply that is not only capable of delivering the energy your project needs, but also keeps it safe from harmful spikes or ripples of electricity. This is why we offer our range of regulated wall-mount Power Supplies, like the AC Adapter 5V 3A Wall Mountwith DC Jack 2.1mm.

This PSU provides 5V at 3A, which is more than enough to handle most Arduino projects, with extra protective features to guard against overload and short circuits. It is black in colour with a w-pin plug on one end and a 2.1mm centre-positive barrel jack on the other, allowing you to plug your projects directly into a wall socket with a 2-pin adapter. This lets you bypass the need for a computer or USB-powered cables, giving you the freedom to take your Electronics projects out into the world to exhibitions or simply to another room without a computer.

Typical Applications for the 5V 3A AC Wall Adapter with DC Jack 2.1mm:

The 2.1mm Jack on these Wall Mount 5V 3A AC Adapters mean that they can be used for a wide range of electronics applications, and most of our customers who purchase these utilize them for Arduino projects typically requiring between 3.3V and 5V DC. The adapter plugs directly into a wall socket via a 2-pin connection and converts any standard 100V – 240V AC supply down to a more manageable power rating. If you’ve been looking for a way to free your Arduino projects from a power source supplied via USB or another computer cable, this is a fantastic yet relatively inexpensive option.
