Description

The Security-01 DC 9V 0.5A power supply adapter delivers reliable power to Arduino boards and compatible microcontroller systems with a centre positive connector configuration. Featuring AC 100-240V input at 50/60 Hz, this adapter converts mains power to a stable DC 9V 0.5A output, making it ideal for hobbyists and developers working with Arduino UNO R3, Arduino Mega 2560, and compatible development boards including IEIK models. The 5.5mm x 2.1mm connector with centre positive polarity ensures secure connection to supported devices, whilst the 2m cable provides convenient reach from power outlets. This adapter is specifically designed for devices requiring centre positive configuration and will not function with equipment using centre negative polarity, such as effects pedals, guitar pedals, keyboards, or drum machines. Perfect for powering prototyping projects, educational electronics work, and Arduino-based applications that demand consistent, clean power delivery.

Key Features

Security-01 adapter provides DC 9V 0.5A (500mA) output suitable for Arduino UNO R3 and Mega 2560 boards.

5.5mm x 2.1mm connector with centre positive polarity ensures compatibility with specified Arduino and microcontroller devices.

2m cable length offers flexibility when positioning power outlets away from your Arduino prototyping workspace.

AC 100-240V 50/60 Hz input accepts standard mains power globally across different voltage regions.

Centre positive design prevents accidental connection to centre negative equipment like guitar pedals or keyboards.
