30POEX_48-A Series

30W - Single Output - Wide Input - Isolated & Regulated

DC-DC Converter

30 Watt

Eﬃciency up to 85%

Meet CISPR22/EN55022

The 30POEX_48-A module is designed to extract power from a conventio-

nal twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3at

Power-over-Ethernet (PoE) standard.

Over load protection

Short circuit protection (SCP)

Operating temperature range:

-40°C ~ +85°C

CLASS A

IEEE 802.3at

SIP & DIP pin-style

The 30POEX_48-A signature and control circuit provides the PoE compati-

bility signature and power classiﬁcation required by the Power Sourcing

Equipment (PSE) before applying up to 30W power to the port.

The 30POEX_48-A is compatible with Class 0 to Class 3 equipment.

The high eﬃciency DC/DC converter operates over a wide input voltage

range and provides a regulated low ripple and low noise output. The DC/

DC converter also has built-in overload and short-circuit output protection.
