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. The series
includes models with output voltages as low as 1.5V. 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.
SPECIFICATION All specifications are typical at nominal input, full load at 25°C unless otherwise stated
