2. Description
The Ag9000-S series of modules are designed to extract power from a conventional twisted pair
Category 5 Ethernet cable, conforming to the IEEE 802.3af Power-over-Ethernet (PoE)
standard.
IEEE 802.3af allows for two power options for Category 5 cables and the Ag9000-S series have
two pairs of power inputs pins: - VA1&2 and VB1&2 to accommodate this, see Figure 1.
The Ag9000-S signature and control circuit provides the PoE compatibility signature and power
classification required by the Power Sourcing Equipment (PSE) before applying up to 15W
power to the port. The Ag9000 is compatible with Class 0 to Class 3 equipment.
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 and
short-circuit output protection.
