Delphi Series E48SB, Eighth Brick Bus Converter

DC/DC Power Modules: 48V in, 240W out

The Delphi Series E48SB, Eighth Brick sized, 48V input, single

output, open frame bus converters are the latest offering from a world

leader in power systems technology and manufacturing -- Delta

Electronics, Inc. This product features an input voltage range of 38V to

55V and provides up to 240 watts of power or up to 25A of output current

in an industry standard footprint. This product represents the next

generation of design technology that supports the intermediate bus

architecture to power multiple downstream non-isolated point-of-load

(POL) converters. With creative design technology and optimization of

component placement, these converters possess outstanding electrical

and thermal performance, as well as extremely high reliability under

stressful operating conditions. All modules carry a full set of international

safety approvals. An optional heatsink is available for extreme thermal

requirements.
