2. Description
The Ag6800 is an IEEE802.3bt Power Sourcing Equipment (PSE) module designed to be
compliant with draft version 3.2. It will also work with lower power IEEE802.3af,
IEEE802.3at power devices and compatible with legacy protocols such as PoH and UPoE.
The Ag6800 is a complete, easy to implement solution for adding POE functionality to a
wide variety of applications requiring higher power up to 97W such as lighting systems,
digital signage, Point-of-Sale systems, LCD TVs, computer monitors and video projectors.
Ag6800 is a self-contained module, requiring just a few external components to provide
the complete control and feedback to the Powered Device (PD) that is connected to the
PSE.
