INFOMART IT SOLUTIONS PEM3012C 模块, 以太网供电, 802.3AF/AT, PD, 12V, 30W
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 802.3atPOE+ and IEEE 802.3af POE compliant Power Sourcing Equipments PSE. The PEM3012 series modules 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 PEM3012 provides a quick, easy, and low cost method for Ethernet equipment manufacturers to PoE enable their equipment.
