Delphi Series Q48DB, 65W Quarter Brick Dual Output
DC/DC Power Modules: 48V in, ±12V Output
The Delphi Series Q48DB Quarter Brick, 48V input, positive and negative
bipolar dual output, and isolated DC/DC converters are the latest offering
from a world leader in power system and technology and manufacturing ―
Delta Electronics, Inc. This product family provides positive and negative
bipolar output (output voltage is 12V) and up to 65 watts of power in an
industry standard quarter brick package size. Both output channels can be
used independently. With creative design technology and optimization o
f
component placement, these converters possess outstanding electrical
and thermal performance, as well as extremely high reliability under highl
y
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.
