Description:
A DC power supply adapter is a device that converts alternating current (AC) from a wall outlet to direct current (DC) at a specific voltage and amperage. This adapter is designed to provide a 12-volt output at 1 ampere, suitable for powering various electronic devices.   
Key Features:
- Input Voltage: Typically 100-240V AC, allowing for worldwide use.
 
- Output Voltage: 12V DC   
 
- Output Current: 1A (1000mA)   
 
- Single Pin Connector: Features a single-pin output connector, commonly used for devices with a corresponding DC jack.
 
- Compact and Lightweight: Designed for portability and easy storage.
 
- Overload Protection: Built-in protection to prevent damage to the adapter and connected devices in case of overcurrent.   
 
- Short Circuit Protection: Protects against short circuits that could occur if the positive and negative terminals are connected.   
 
- Overvoltage Protection: Protects against voltage spikes that could damage connected devices.   
 
Specifications:
- Input Voltage: 100-240V AC, 50/60Hz   
 
- Output Voltage: 12V DC   
 
- Output Current: 1A (1000mA)   
 
- Connector Type: Single Pin 
 
- Efficiency: Typically around 80-90%
