Evaluation Procedure
Delta Delphi Series 48Vin
S48SR and S48SS
The Delphi Series S48SR and S48SS,
48V input, single output, isolated DC/DC
converters are the latest offering from one
of the world’s largest power supply
manufacturers
―
Delta Electronics, Inc.
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. All models
are protected from abnormal input/output
voltage and current conditions. An
encapsulated version is available for the
most robust performance in harsh
environments.
This document guides the user through the
evaluation procedures to qualify a Delphi
module. The data shown in this Evaluation
Procedure is for the 3.3V unit. Please refer
to the appropriate technical data sheet for
detailed performance and technical
information for Delphi units with different
output voltages.
