2. Description
The Ag5800 is an IEEE802.3bt Power over Ethernet module that can deliver up to 85 Watts* of
output power when connected to an IEEE802.3bt PSE. Suitable for applications such as PTZ
IP cameras, LED lighting, door access systems, intelligent displays and sensors, monitors and
projectors.
The modules input conforms to the IEEE 802.3bt (Draft V3.2) standard for signature
recognition and class programming. It has been designed to work with IEEE802.3bt and
existing high power PSE’s from leading manufacturers.
The high efficiency DC/DC converter operates over a wide input voltage range and provides a
regulated low ripple and low noise output. The DC/DC converter also has built-in overload,
thermal and short-circuit output protection.
*See section 5.6- Output Power
