About Power over Ethernet (PoE) Controllers
Power over Ethernet (PoE) controllers are used to control the delivery of DC power and data from power source equipment (PSE) to powered devices (PD). They perform PD detection and classification, -48 V power distribution, and fault protection on multiple channels. Some PoE controllers can manage power autonomously, without the intervention of a host controllers. Others can implement AC or DC disconnect techniques as specified in the IEEE 802.3af, the power distribution standard from the Institute of Electrical and Electronics Engineers (IEEE) which defines PoE technology. Power over Ethernet (PoE) controllers have two main parts: PoE switches and PoE adapters. Power over Ethernet (PoE) switches are powered from an integral DC terminal block. Power over Ethernet (PoE) adapters consist of a base unit and a terminal unit. Typically, the base unit plugs into the power outlet. The terminal unit is connected to the network device through the Ethernet cable.
