PEM3100 SERIES

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

. Up to 30Watt output load¹

. 1500 Volt DC isolation (Input to Output)

. Overload protection²

. IEEE Power class 4

. Continuous short circuit protection

. Low output ripple and noise

. High efficiency

. Compact package horizontal mounting

. Minimal external components required

. Cost effective

. 12V, 18V and 24V DC output voltage models

. Adjustable output voltage

. Support for external aux. power supply

. RoHS 2002/95/EC compliant

. “AT Detect” pin for layer 2 classification

¹30watt peak for maximum 30sec. at duty cycle of 10%. Please see

section F.9. – Thermal profile on operating temperature.

²If maximum power is exceeded, the PEM3100 will operate in an

over current mode and will auto recover when the over load

condition is removed.
