The minimum power mandated for Class 4 Power Sourcing Equipment (PSE) is indeed 30 W. This classification is part of the Power over Ethernet (PoE) standards, which specify how much power can be delivered over Ethernet cables to connected devices. Class 4 was designed to accommodate more demanding devices that require greater power than what the earlier classes could provide.

Class 1 and Class 2 provide 4 W and 7 W, respectively, primarily for low-power devices like IP cameras and VoIP phones. Class 3 offers up to 15.4 W, which is still aimed at less power-intensive applications. In contrast, Class 4, with its 30 W minimum requirement, supports more power-hungry devices such as wireless access points and higher-performance IP cameras, which can benefit from increased power for improved functionality and performance.

This framework enables a range of devices to be powered through the same cable that carries data, streamlining installations and reducing the need for separate power supplies.
