5V 3A DC Power Supply 2.1mm – AU Plug

Power your low-voltage electronics reliably with this compact 5V 3A power supply (also known as a plugpack). Designed for devices requiring a stable 5V DC input, it connects directly to Australian mains power (240V AC) and features a standard AU 2/3-pin plug for seamless compatibility. The output jack uses a common 2.1mm DC barrel tip, ideal for a wide range of electronics.

Whether you're powering microcontroller boards, USB-powered gadgets, or LED lighting, this supply delivers consistent performance.

Specifications:

• Input Voltage: 240V AC (Australian mains power)
• Output Voltage: 5V DC
• Maximum Output Current: 3A
• Connector: 2.1mm DC barrel plug
• Plug Type: AU 2/3-pin plug – suitable for Australian outlets
• Use: Indoor use only

How to Choose the Right Power Supply:

To determine if this 5V 3A supply is suitable for your device, calculate the required wattage using the formula:

Wattage (W) = Voltage (V) × Current (A)
Example: A 5V device that draws 0.8A requires 4W. A 5V 1A (5W) supply is sufficient, and it’s recommended to include a 10–20% safety margin.

Important Notes:

• Voltage must match exactly. This power supply is only suitable for devices that operate at 5V.
• Current can be higher, not lower. Your device will only draw what it needs; having a higher current rating ensures stable performance.
• Indoor use only. This adapter is not waterproof or weather-resistant.

Ensure your devices are powered safely and efficiently with this reliable 5V power supply.

Note: Size/design of power supply may vary
