Delphi Series Q48DR, 87W-100W, Quarter Brick
Dual Output, DC/DC Power Modules:
48V in, 1.5V and 3.3V, 15A out each channel
The Delphi Series Q48DR Quarter Brick Dual, 48V input, dual output,
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 up to 100 watts of power or 15A of
output current (each channel simultaneously) in an industry standard
footprint. Both output channels can be used independently of each other
with option to trim each channel either in the same direction or in
reversion direction. With creative design technology and optimized
circuit, these converters possess outstanding electrical and thermal
performance, as well as extremely high reliability under highly stressful
operating conditions. All the models are fully protected from abnormal
input/output voltage, current, and temperature conditions. The Delphi
Series converters meet all safety requirements with basic insulation.
