12V 2A Power Adapter

12V 2A Power Adapter is a high-efficiency regulated AC-to-DC switching power supply designed to deliver a steady 12 Volt DC output at up to 2 Amperes (24 Watts) of continuous current. Featuring a wide universal input voltage range (100V–240V AC) and the industry-standard 5.5mm x 2.1mm center-positive DC coaxial barrel plug, this compact adapter easily powers a broad spectrum of electronic equipment. Built with internal over-voltage, over-current, and short-circuit protection, it is an essential power supply for Wi-Fi routers, ONUs, CCTV cameras, LED light strips, Arduino development boards, and various robotics projects.

Features

• Regulated 12V DC output providing clean, low-ripple power for sensitive microcontrollers and audio/video electronics
• Industry-standard 5.5mm outer diameter and 2.1mm inner pin coaxial barrel plug (Center Positive +)
• Universal AC input voltage range (100V to 240V AC) compatible with global power grids
• High conversion efficiency with low standby power consumption and minimal operating heat
• Integrated multi-tier circuit protection against over-voltage, over-current, thermal overload, and short circuits
• Compact wall-mount plug design saving space on power strips and extension sockets
• Durable flame-retardant ABS plastic casing with integrated strain relief for long-lasting usage

Applications

• Primary power source for Wi-Fi routers, broadband ONUs, modems, and network switches
• Powering CCTV security cameras, DVR systems, and access control hardware
• Driving 12V flexible LED strip lights, cabinet lighting, and display signage
• Benchtop power supply for Arduino mega/uno boards, motor drivers (L298N, TB6600), and 12V relays
• Polytechnic diploma, university engineering thesis, and custom electronics prototyping

Important Notes:

• Polarity Compatibility: Always ensure your target device requires a Center-Positive (+) polarity before plugging in the adapter to prevent reverse-polarity damage to your electronics.
• Current Budgeting: This adapter delivers up to 2A max. It can easily power devices requiring less current (e.g., 500mA, 1A, 1.5A), but should not be connected to heavy loads demanding more than 2A continuous draw.
• Indoor Use Only: Keep the power adapter body dry and protected from rain, extreme humidity, or direct heat sources.

Package includes

• 1 x 12V 2A Regulated DC Power Adapter (5.5mm x 2.1mm Barrel Plug)
