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
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- 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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
