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. The series includes models
with output voltages as low as 1.5V. 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.
