Ag9205S Silvertel

V1.7 October 2009 Datasheet Ag9200-S Silvertel Power-Over-Ethernet Module 1 Features PbPb IEEE802.3af compliant Small SIL package size - 56mm (L) x 14mm (H) Low output ripple and noise Input voltage range 36V to 57V Minimal (low cost) external components required Overload and short-circuit protection Adjustable Output Higher efficiency DC/DC converter 1500V isolation (input to output) Silvertel design-in assistance 2 Description The Ag9200 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. The Ag9200 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 Ag9200 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.
