In Power over Ethernet (PoE), what is the power capacity of Class 3 devices?

Class 3 devices in Power over Ethernet (PoE) have a power capacity of 15.4 Watts. This classification is part of the IEEE 802.3af standard, which specifies the characteristics of PoE, including the amount of power that can be delivered to devices over standard Ethernet cabling.

PoE Classifications are designed to categorize the power requirements of various networked devices. Class 3 is particularly suited for devices that require more power than those in Class 1 or Class 2, making it ideal for equipment like IP cameras and certain types of wireless access points that have moderate power needs. The ability to deliver up to 15.4 Watts means that Class 3 devices are robust enough to support a significant range of functionalities while still adhering to the power restrictions of PoE technology.

Understanding these classifications is crucial for network installation and management, ensuring that the right power supply is provided to all connected devices, enhancing functionality and network stability.
