2 YEAR WARRANTY

BXF200 Series

Single output

BXF200 Series high power density DC/DC converters can provide up to 40A 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. BXF200 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 BXF200 Series is approved by UL, CSA and VDE.

All specifications are typical at nominal input, full load at 25°C unless otherwise stated
