l Description: The RT7800 series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af at Power-overEthernet(PoE) standard. The RT7800 signature and control circuit provides the PoE compatibility signature and power classification required by the Power Sourcing Equipment (PSE) before applying up to 15W(af) 30w(at) power to the port. The RT7800 provides a Class 0 (af) Class(4) signature. The RT7800 DC/DC converter operates over a wide input voltage range and provides a regulated output. The DC/DC converter also has built-in short-circuit output protection.
l Application: ·IP Cameras ·Wireless access point ·Security and alarm systems ·VOIP telephone ·Point of sale network terminal equipment
