Ericsson introduces highly robust power modules with ultra-wide input voltage range for industrial applications

New highly robust PKE3000PI and PKE5000PI DC/DC converters suited to deployment in industrial and railway applications and also suitable for remote power feed applications. Ultra wide input voltage ranges means new module accommodates 12V, 24V and 48V systems, delivering design flexibility for engineers and also reducing inventories. Highly robust, new industry-standard-sized compact converters offered in encapsulated packages for harsh environments.

Ericsson has introduced two new series of DC/DC converter modules that are primarily aimed at industrial and railway transportation applications, as well as information and communications technology (ICT) applications that are operated with remote power supplies and/or multiple battery voltages. Ideally suited to use in distributed power architectures and industrial control systems, these new highly robust modules target typically 12V, 24V or 48V power supply line applications that require a board power supply to operate across a large range of input voltages, and without disrupting output characteristics when the input line is experiencing very high fluctuation.

"In the industrial arena in particular, many applications require an ultra-wide-input voltage to handle a large variety of power sources, said Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules. "These new compact and highly robust DC/DC converter enable the possibility to use a single module to accommodate at least two different battery voltages with a single module, thereby reducing inventory and also delivering flexibility for designers that are developing single boards to handle different voltage sources."

In addition, the modules meet requirements for board development purposes or remote-feed applications where voltages are delivered to the load via long cables. In this case, the board power converter is required to secure stable input voltage whatever the length of cable and wherever the board is connected.
