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. PRODUCT FEATURES Fully IEEE 802.3at and 802.3af compliant 1500 Volt DC isolation (Input to Output) 1 2 Up to 30Watt output load Overload protection IEEE Power class 4 Continuous short circuit protection High efficiency Low output ripple and noise Compact package horizontal mounting 12V, 18V and 24V DC output voltage models Minimal external components required Adjustable output voltage Cost effective Support for external aux. power supply AT Detect pin for layer 2 classification RoHS 2002/95/EC compliant 1 2 30watt peak for maximum 30sec. at duty cycle of 10%. Please see If maximum power is exceeded, the PEM3100 will operate in an section F.9. Thermal profile on operating temperature. over current mode and will auto recover when the over load condition is removed. www.poweredethernet.com PEM3100 13F R1-1 Page 1 of 13 PEM3100 SERIES by 30W Power Over Ethernet Plus (POE+) PD Module TABLE OF CONTENTS PRODUCT OVERVIEW ............................................................................................................
