1008W Isolated Quarter Brick DC-DC Converter
The iQK series of isolated DC-DC converters provide a fully regulated 11.2V output. Rated at 1008W, the quarter brick sized module can deliver up to 90A output
current. Its 48 to 56Vdc input range is suitable for use with regulated 48V front end supplies, primarily employed in computing, server and data communications
applications. Featuring a high efficiency of up to 97%, it is ideal for use in distributed power architectures.
