BXF400 Series high power density DC/DC converters can provide up to 80A output
current and have an industry-standard footprint, measuring just 2.40 x 4.60 x 0.52 inches.
These converters have the highest output current rating of any comparably-sized
products on the market, are equally suitable for new designs or as replacement power
sources in existing equipment. BXF400 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 BXF400 Series is approved by UL, CSA and VDE.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
