Delphi Series E48SR, 66W Eighth Brick Family
DC/DC Power Modules: 48V in, 15V/4A out
The Delphi Series E48SR Eighth Brick, 48V input, single output, isolated
DC/DC converter is the latest offering from a world leader in power
systems technology and manufacturing — Delta Electronics, Inc. This
product family provides up to 66 watts of power or 25A of output current
(1.8V and below) in an industry standard footprint. With creative design
technology and optimization of component placement, these converters
possess outstanding electrical and thermal performances, as well as
extremely high reliability under highly stressful operating conditions.
All
models are fully protected from abnormal input/output voltage, current,
and temperature conditions. The Delphi Series converters meet all safety
requirements with basic insulation.
