The BXB75 Dual is a high power density DC/DC converter packaged in the
industry standard footprint (2.40 x 2.28 x 0.50 inches). With no minimum load
requirements, either output can supply its maximum current, or both channels can
support any combination of loading to a total of 60/75W of output power. Suitable
for a wide range of applications in nearly any industry, the BXB75 Dual was
designed with communication and distributed power applications in mind.
Aluminum baseplate technology with four threaded inserts makes heatsink
attachment and optimum thermal management easy. The BXB75 Dual series is
approved to IEC950 by UL, CSA and VDE.
