PEM3112C

PEM3112C is a Power Over Ethernet Powered Device (PD) power extraction module, have complete compliance with the high power IEEE 802.3at Power-Over-Ethernet Plus (PoE+) standard, and is designed to extract power from CAT5 Ethernet cable when sourced by both IEEE 802.3at(POE+) and IEEE 802.3af (POE) compliant Power Sourcing Equipments (PSE). The PEM3112C module provide full two event PoE+ and single event POE signature for layer 1 classification and supports layer 2 classification via an AT Detect pin. Its high efficiency DC/DC converter provides up to 30W of power in a well regulated, low noise and low ripple output with in built in rush current, overload and output short circuit protection. The PEM3112C provides a quick, easy, and cost effective method for Ethernet equipment manufacturers to PoE enable their equipment.
