AdAdapter Fixed 12Vdc 1A
🔌 Fixed 12 V DC Power Adapter – 1 A
🔎 Overview
A compact, switch-mode wall-mounted power adapter designed to deliver a steady 12 V DC output at up to 1 A (12 W). It’s widely used for powering electronics like Arduino-based projects, sensors, LED strips, CCTV cameras, routers, and other low-current devices
⚙️ Key Features
AC Input: 100–240 V, 50–60 Hz (universal worldwide)
DC Output: Fixed 12 V ±5%, 1 A (12 W)
Connector: Standard barrel plug (5.5 × 2.1 mm or 5.5 × 2.5 mm), center‑positive
Protections: Over-current, short-circuit, over-voltage, and thermal shutdown
Efficiency: Typically ≥ 80 %, using regulation to avoid excess heat
Cable: Approximately 1–1.5 m long
Operating Temperature: 0–40 °C; storage –20 °C to +70 °C
🔧 Usage
Barrel plug wiring:
CopyEditCentre → +12 V Outer → GND
Plug into wall AC outlet; LED indicator lights up when the adapter is powered
Connect to your load—ensure it draws ≤ 1 A
Common GND required if powering Arduino and peripherals; Arduino can be powered via its barrel or VIN pin
🎯 Applications
Powering Arduino boards and shields via VIN or DC jack
Supplying LED strips, CCTV or router devices
Running 12 V motors, sensors, and relays (with transistor driver)
General-purpose DC power for bench tests and prototypes
