Delphi Series E48SH, 120W Eighth Brick Family
DC/DC Power Modules: 48V in, 1.0V~15V out, 50A max
The Delphi Series E48SH Eighth Brick, 48V input, single output,
isolated DC/DC converters are the latest offering from a world leader in
power systems technology and manufacturing ―Delta Electronics, Inc.
This product family is available in either a through-hole or surface-
mounted package and provides up to 120 watts of power or 50A o
f
output current (1.2V and below) in an industry standard footprint and
pinout. The E48SH converter operates from an input voltage of 36V to
75V and is available in output voltages from 1.0V to 15V. Efficiency is
up to 93.5% (12V output). With creative design technology and
optimization of component placement, these converters possess
outstanding electrical and thermal performance, as well as extremely
high reliability under highly stressful operating conditions.
A
ll models
are fully protected from abnormal input/output voltage, current, and
temperature conditions. The Delphi Series converters meet all safety
requirements with basic insulation.
