12V 5A switching power supply
Warning: This power supply ships with a US/Canada/Japan plug. It is not certified for use in Australia. You can use a plug adapter or replace the cable with...
A high-capacity 12V 5A (60W) switching power supply for projects that need serious current. Accepts 110V or 220V AC input, with a 2.1 mm DC barrel jack output and a green indicator LED.
Ideal for powering LED strips, CNC motor drivers, and other high-current 12V loads. Using a dedicated 12V supply like this avoids the instability of repurposed ATX power supplies, which often have poorly regulated 12V rails when the 5V output isn't also loaded.
Key Features
- 12V DC at 5A – 60W continuous output
- Universal Input – 110V–220V AC (US plug included)
- 2.1 mm DC Barrel Jack – Standard centre-positive connector
- Power Indicator – Green LED confirms operation
- UL Approved
Ideal For
- LED strip lighting installations
- CNC motor drivers and stepper controllers
- High-current 12V electronics and robotics
- Projects needing a stable, dedicated 12V rail
Package Contents
- 1× 12V 5A Switching Power Supply (US plug, figure-8 cable)
Jargon buster
Plain-language definitions for the technical terms used above.
- DC barrel jack
- A round power connector commonly used for low-voltage DC power supplies, often described by its outer and inner diameters such as 5.5 x 2.1 mm. Matching the barrel size and polarity is important so the plug physically fits and powers the device correctly.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
