This is the POE (Power Over Ethernet) module fro the Arduino Ethernet Shield. It allows the Ethernet Shield to be powered directly by a Cat5 LAN cable as part of a POE system.
Our Code: MCU-60082
The Ag9120-S is a module 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 module is shown to the right fitted to an Arduino Ethernet shield
The Ag9120-S 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 high efficiency DC/DC converter operates over a wide input voltage range (36V to 48V typ) and provides a regulated low ripple and low noise output. The DC/DC converter also has built-in overload and short-circuit output protection.
This module could be used with the Arduino Ethernet shield
