Ultra-wide-input DC-DC converters for industrial and railways applications

Flex Power Modules has introduced the PKE-A series of DC-DC power modules for the industrial and railways sectors, expanding its product range to satisfy a growing need in these sectors. The modules are presented in sealed and encapsulated packaging, to guarantee they will work reliably when subjected to moisture, dust, severe vibration and other harsh conditions. For industrial applications, the PKE8000A series offers highly reliable, high-performance and rugged DC-DC solutions in the industry-standard 2" x 1" form factor, operating from 12V, 24V or 48V supply voltages thanks to its ultra-wide-input range of 9V to 75V. Giving up to 40W of output power at up to 91% efficiency, the series also provides MTBF of up to four million hours and input-to-output isolation of 2250VDC. The devices satisfy the latest IEC/EN/UL62368-1 safety standards. For railways applications, the PKE7000A series is packaged in the same 2 x 1" industry-standard form factor, but this time works from a 43V to 160V input, producing up to 30W. This makes it ideal for the bulk of onboard demands running from 72V and/or 110V nominal supplies, most often found in the railways sector. The devices comply with the EN50155 railway standard and offer MTBF figures of up to five million hours to meet the most exacting applications. Olle Hellgren, director of Product Management and Business Development at Flex Power Modules, commented: “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.”
