BXF300 Series high power density DC/DC converters can provide up to 60A output
current and have an industry-standard footprint, measuring just 2.40 x 4.60 x 0.52
inches. The converters are equally suitable for new designs or as replacement power
sources in existing equipment. BXF300 Series converters are designed specifically for
redundant and distributed power systems in the computer and telecommunications
sectors, but their feature-rich specifications make them suitable for a very wide range
of applications. Using Bellcore 332, the MTBF is over 1,000,000 hours. Aluminium
baseplate technology and four threaded M3 inserts make heatsink attachment and
thermal management easy. The BXF300 Series is approved by UL, CSA and VDE.
