PEM3112C Datasheet, PDF (1/13 Pages) List of Unclassifed Manufacturers – 30W Power Over Ethernet Plus (POE) PD Module

PEM3100 SERIES
by
30W Power Over Ethernet Plus (POE+) PD Module
PRODUCT OVERVIEW
The PEM3100 series of Power Over Ethernet Powered Device (PD) power extraction modules, have
complete compliance with the high power IEEE 802.3at Power-Over-Ethernet Plus (PoE+) standard, and
are 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 PEM3100 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 30 watts 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 PEM3100 series provides a quick, easy, and cost effective method for manufacturers of Ethernet
equipment like PTZ cameras, WiMAX^®tower and access points, Wireless N, RFID readers, POS terminals,
thin client terminals, and IP telephones to “PoE enable” their equipment.
