The Ag9300 Power-over-Ethernet (PoE) module is designed to extract power from a conventional
twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af PoE standard. With an
additional auxiliary input that will accept a DC or AC voltage.
This module is ideal for security cameras where 12Vdc or 24Vac is used. It can also be used with
other security systems such as door access or sensors that have an input voltage of 12Vdc to
48Vdc or 18Vac to 30Vac.
The Ag9300 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 Ag9300 is compatible with Class 0 to Class 3 equipment.
The high efficiency DC/DC converter operates over a wide input voltage range with a low ripple
and low noise output. The DC/DC converter also has built-in output overload, output short-circuit
and over-temperature protection and provides a 1500Vdc (input to output) isolation barrier.
