Ag9712-FL

V2.3 Apr 2015 Datasheet Ag9700 Silvertel Power-Over-Ethernet Module 1. Features PbPb IEEE802.3af compliant Small SIL and SMT package available Low cost, with minimal external components required Input voltage range 36V to 57V Short-circuit protection Adjustable output 1500V isolation (input to output) High performance option available with classification programming, industrial temperature range and thermal protection (Ag9700-FL) Silvertel design-in assistance 2. Description The Ag9700 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 Ag9700 signature and control circuit provides the PoE compatibility signature required by the Power Sourcing Equipment (PSE) before applying up to 15W power to the port. By default all variants of the Ag9700 provides a Class 0 signature but the Ag9700-FL has the additional feature of classification programming. The DC/DC converter operates over a wide input voltage range and provides a regulated output. The DC/DC converter also has built-in short-circuit output protection.
