40W DC-DCs for Industrial and Railway Applications

April 24, 2019 by Scott McMahan

Flex Power Modules introduced the PKE-A series of dc-dc power modules for industrial and railway applications. The modules come in sealed and encapsulated packaging that ensures they will work reliably even when subjected to moisture, dust, severe vibration, and other harsh conditions.

The PKE8000A series offers highly reliable, high-performance, and rugged dc-dc solutions in the industry-standard 2in x 1in form factor. The series runs from 12V, 24V, or 48V supply voltages thanks to its wide input range of 9V to 75V.

Delivering up to 40W of output power at up to 91% efficiency, the series also has input-to-output isolation of 2250Vdc and has a mean time between failures (MTBF) of up to 4 million hours.

The devices meet the most recent IEC/EN/UL62368-1 safety standards.

Railway Application Variants

For Railway applications, the PKE7000A series is packaged in the same 2in x 1in industry-standard form factor, but these variants operate from a 43V to 160V input and deliver up to 30W. The standard size and 43V to 160V input range make the series suitable for the majority of onboard requirements running from 72V and/or 110V nominal supplies, most often used in the railway sector. The devices comply with the EN50155 railway standard and offer MTBF figures of up to 5 million hours that satisfy the most demanding applications.

"The PKE-A series is just one of a wide range of new products we are introducing to support Industrial and Railways applications, and is a crucial part of our previously announced push into these important market segments," Olle Hellgren, Director of Product Management and Business Development at Flex Power Modules, said.


  • 9V to 75V and 43V to 160V inputs capture wide range of applications within the industrial and railway markets
  • Runs from 3.3V, 5V, 12V, 15V, 24V, and 48V supply voltages
  • Outputs up to 40W
  • Encapsulated 2in x 1in packaging for reliable operation in harsh conditions

Both the PKE8000A and PKE7000A families are available now for sampling and volume production requirements.
