Wide input DC-DC power modules for industrial and railway designs in sealed and encapsulated packaging.
Flex Power Modules has launched a series of wide input DC-DC power modules for industrial and railway designs in sealed and encapsulated packaging.

For railway designs, the wide input DC-DC PKE7000A series is packaged in the same 2 x 1in industry-standard form factor, but this time operates from a 43 to 160V input, delivering up to 30W. This makes it suitable for the majority of onboard requirements running from 72V and/or 110V nominal supplies, most commonly found in the Railways sector. The devices comply with the EN50155 railway standard and offer MTBF figures of up to 5 million hours to satisfy the most demanding applications.

For Industrial applications, the PKE8000A series provides highly reliable, high-performance and rugged wide input DC-DC solutions in the industry-standard 2 x 1in form factor, running from 12V, 24V or 48V supply voltages thanks to its ultra-wide-input range of 9 to 75V. Delivering up to 40W of output power at up to 91% efficiency, the series also offers mean time between failures (MTBF) of up to 4 million hours, and input-to-output isolation of 2250VDC. The devices meet the latest IEC/EN/UL62368-1 safety standards.

“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,” said Olle Hellgren, Director of Product Management and Business Development at Flex Power Modules. 

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