Which class of PoE delivers 30 Watts of power?

The class of Power over Ethernet (PoE) that delivers 30 Watts of power is classified as High PoE+, also known as IEEE 802.3at or PoE+. This classification allows for a maximum output power of up to 30 Watts, catering to devices that require more substantial power than what standard PoE can provide.

Standard PoE, as defined by IEEE 802.3af (also known as PoE), typically delivers up to 15.4 Watts, while PoE Class 2, which generally falls under the same standard, provides a slightly higher power level, around 30 Watts, but is still in the context of differing definitions and isn’t the one designated for higher demand devices. Class 3 can provide up to 15.4 Watts as well.

The High PoE+ class ensures that more power-hungry devices, such as PTZ (pan-tilt-zoom) cameras, VoIP phones with heated displays, and wireless access points, can operate efficiently. Understanding the classification of PoE is critical for ensuring that devices are powered appropriately and that the network infrastructure can support the required power levels for various applications.
