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

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.

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.
