PEM3000 SERIES by 30W Power Over Ethernet Plus (POE+) PD Module PRODUCT OVERVIEW The PEM3000 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 PEM3000 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 PEM3000 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 2 Fully IEEE 802.3at and 802.3af compliant Overload protection 1 Up to 30Watt output load Continuous short circuit protection IEEE Power class 4 Low output ripple and noise High efficiency 12V, 18V and 24V DC output voltage models Compact package minimum PCB footprint Adjustable output voltage Minimal external components required Support for external aux. power supply Cost effective RoHS 2002/95/EC compliant AT Detect pin for layer 2 classification 2 1500 Volt DC isolation (Input to Output) If maximum power is exceeded, the PEM3000 will operate in an over current mode and will auto recover when the over load condition is removed. 1 30watt peak for maximum 30sec. at duty cycle of 10%.
