Enhanced 50W ultra-wide-input power module in sixteenth-brick footprint simplifies Power-over-Ethernet (PoE) applications. Ultra-wide input voltage from 18V to 75V means new module accommodates 24V and 48V systems, reduces inventories and is also suitable for remote power feed applications. Enhanced thermal layout improves power-dissipation in low-airflow applications. 2250Vdc isolation matches Power-over-Ethernet specifications.

Ericsson has introduced a new 50W DC/DC converter module that targets Power-over-Ethernet (PoE) applications. Very importantly, the new Ericsson PKU5510E converter features an ultra-wide input range of 18V to 75V, which means that the device is also suitable for 24V or 48V telecom systems. The module is the latest evolution of Ericsson’s PKU family and combines the thermal enhancements integrated in the recently announced PKU4116C module together with an optimized fly-forward topology, which was first introduced by Ericsson in 2008. The PKU5510E delivers an output current of 15A at 3.3V output and has a built-in functional isolation of 2250Vdc that meets the requirements specified by the IEEE802.3 Ethernet networking standard, and also meets Basic Insulation requirements according to IEC/EN/UL60950.

"The growing market for Power-over-Ethernet based applications is a highly demanding one," said Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules. "It requires cost-efficient and high-efficiency power products such as the PKU5510E, which benefits from Ericsson advanced R&D and integrates a best-in-class thermal layout with an advanced power topology to deliver industry-leading performance."

The PKU5510E has been designed for applications that have to accommodate both telecom system bus voltages of 24V and 48V, while also being a best-in-class product to supply voltages to Power-over-Ethernet based applications such as remote antennas, WIFI repeaters, basestation microcells, CCTV/camera monitoring systems and a variety of different sensors.
