What are Power Over Ethernet (PoE) Controllers ?
Power Over Ethernet (PoE) Controllers are integrated circuits that manage power delivery over Ethernet networks, allowing devices to receive power and data simultaneously. They are commonly used in applications such as industrial power management and production electronics assembly. Important specifications for selection include Current, which affects the power capacity; Operating Temperature, which ensures reliability in various environments; and Number of Channels, which determines the number of devices that can be powered. Procurement teams should validate lifecycle status and consider alternate-source options to mitigate sourcing risks.
