Power Over Ethernet (PoE) Controllers are designed to facilitate the transmission of electrical power and data over Ethernet cables simultaneously. These controllers are commonly used in networking equipment such as switches, routers, access points, IP cameras, and VoIP phones to provide power to connected devices without requiring separate power cables. PoE controllers adhere to IEEE standards like 802.3af, 802.3at (PoE+), or proprietary standards, delivering power efficiently and safely over Ethernet infrastructure. The pricing of PoE Controllers can vary based on several factors such as the power output capability, support for PoE standards (e.g., 802.3af, 802.3at), integration of additional features (e.g., surge protection, thermal management), and brand reputation. Higher-power PoE controllers capable of delivering more watts to connected devices may have higher price points. When purchasing PoE Controllers, assess the power requirements of your PoE-enabled devices and choose a controller with sufficient power output and compatibility with PoE standards required by your devices. Consider features such as surge protection, overcurrent protection, and thermal management to ensure safe and reliable power delivery. Evaluate compatibility with Ethernet standards, interface options for configuration and monitoring, and support for features like power sourcing equipment or powered devices.
