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