PoE power supplies

What are PoE power supplies? 

PoE power supplies are devices that allow you to power network devices such as IP cameras, Wi-Fi access points or VoIP phones via a standard Ethernet cable. This means you do not need to install additional power cables, simplifying installation and reducing costs. PoE power supplies are ideal for both the home and office, where it is important to combine power and data in a single cable. 

Types of PoE power supplies 

• Lower power supplies - are power supplies ideal for less demanding devices such as small IP cameras or Wi-Fi access points. They offer stable power while transmitting data, making them ideal for simple network installations. 

• Medium power supplies - These power supplies are designed for devices that require more power, such as more advanced IP cameras with PTZ (pan, tilt, zoom) or VoIP phones. They provide reliable power and can support more devices simultaneously. 

• Higher power supplies - designed to supply power to more demanding network equipment, such as large access points or cameras with higher power requirements. These power supplies provide the high performance and stability required for professional installations. 

How do I choose the right PoE power supply? 

1. Output power and voltage: The choice of PoE power supply depends on the power and voltage requirements of the devices you want to power. If you need a power supply for standard 24V devices, a good choice would be Extralink POE 24V 1A ZAS-068. For more demanding applications, where more power is needed, it is worth considering Extralink POE 24-24W-Gwhich offers 24W of power. 

2. Compatibility with devices: Make sure the PoE power supply you choose is compatible with your network equipment. For example, the power supply Extralink POE 18-18W will be suitable for devices requiring up to 18W, making it ideal for smaller IP cameras or access points. 

3. Number of devices: If you plan to power more than one device, pay attention to the power supply's wattage. The higher wattage the power supply offers will allow you to stably power several devices at the same time, which is crucial in larger installations.
