Delphi Series E36SR, 75W Eighth Brick Family
DC/DC Power Modules: 18~75V in, 5V/15A out
The Delphi Series E36SR Eighth Brick, 18~75V 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 operates from an extremely wide 18~75V input range
and provides up to 75 watts of power in an industry standard eighth brick
footprint and pinout. With creative design technology and optimization o
f
component placement, these converters possess outstanding electrical
and thermal performances, as well as extremely high reliability unde
r
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.
