SKM30-N/DKM30-N Series: 30W 2〞x 1 〞Wide Range Input Isolated DC-DC Converter

By: Frank Chen / Product Manager

MEAN WELL's SKM30 series is a 2”x 1” DC-DC converter with 2:1 input range, which has been on the market for more than 10 years. In order to fulfill wider input range requirements, MEAN WELL is proud to launch our new 4:1 wide range input single output SKM30-N and dual output DKM30-N series that keep the same footprint as the older series. These features make these converters suitable for electrical panels, telecommunication equipment, industrial control, distributed power architecture, and transportation applications.
