DC/DC CONVERTERS 72-132W Wide Input DC/DC Converters
1
• Board mounted full brick with industry standard footprint
• Adjustable output voltage with output currents of 40A
• 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
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.
