Delta Electronics, Inc.
Delphi Series Q48SR, 165W Quarter Brick Family
DC/DC Power Modules: 48V in, 3.3V/50A out
The Delphi Series Q48SR Quarter Brick, 48V input, adjustable single
output, isolated, open frame DC/DC converters are the latest offering
from a world leader in power systems technology and manufacturing —
Delta Electronics, Inc. This product family provides up to 165 watts of
power or up to 60A of output current in an industry standard footprint.
This product represents the next generation of design technology which
may be utilized to provide high levels of current at very low output
voltages required by today’s leading-edge circuitry. Utilizing an advanced
patented thermal and electrical design technology; the Delphi Series
Q48SR converters are capable of providing higher output current
capability with excellent transient response and lower common mode
noise. Featuring a wide operating output voltage range and high current
at low output voltages, these units offer more useable power over a wide
range of ambient operating conditions. The wide range trimmable output
feature allows the user to both reduce and standardize part numbers
across different and/or migrating voltage requirements. This model
covers the output range of 1.7V to 3.6Vat 50A.
