BXF250 Series

S i n g l e o u t p u t

DC/DC CONVERTERS 90-165W Wide Input DC/DC Converters

• Board mounted full brick with industry standard footprint

• Adjustable output voltage with output currents of 50A

• No minimum load required

• 2:1 input range for battery powered applications

• Synchronizable and parallelable with load sharing

• Overtemperature and short circuit protection

• Current monitor and power good signal

• Remote ON/OFF

• ISO9001 certified manufacturing facilities

BXF250 Series high power density DC/DC converters can provide up to 50A 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. BXF250 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 BXF250 Series is approved by UL, CSA and VDE.
