Detailed Description
Voltage and Current Output
- Voltage:
- Supplies a consistent 12V DC output, crucial for devices that require this exact voltage to operate safely.
- Amperage:
- Comes in various current ratings such as 12V 0.5A, 1A, 2A, or higher.
- The adapter’s amperage must meet or exceed the device’s requirements; for example, a 12V 1A adapter can power devices needing up to 1A, but not higher.
Input Power
- Compatible with global AC power standards:
- Input Voltage: 100-240V AC.
- Frequency: 50/60Hz.
- Universal input range allows for international use with appropriate plug adapters.
Connector Design
- DC Barrel Plug:
- Common sizes include 5.5mm outer diameter / 2.1mm inner diameter.
- The polarity is usually positive-center, indicated on the adapter or device (e.g., “+---(•---”).
Build Quality and Safety Features
- Constructed with durable, fire-retardant materials for reliability.
- Equipped with multiple safety features:
- Overcurrent protection to prevent excessive power draw.
- Overvoltage protection to shield the connected device from voltage spikes.
- Short-circuit protection to avoid damage in case of wiring faults.
- Thermal protection to prevent overheating.
Cable Length
- Typically ranges from 1.5 meters to 3 meters, ensuring flexibility in placement.
Plug Type
- Available in regional variants (e.g., Type A for the US, Type C for Europe) or as universal adapters with interchangeable plug heads.
Applications
- Primary Use:
- Powering networking equipment like routers, modems, switches, and access points.
- Other Uses:
- Compatible with security cameras, LED strips, small appliances, or other devices needing 12V DC power.
Advantages
- Efficient and Reliable:
- Maintains consistent power output for uninterrupted device operation.
- Compact and Lightweight:
- Easy to transport and store.
- Versatile Compatibility:
- Works with a wide range of devices requiring 12V DC power.
