Delta Electronics, Inc.
Delphi Series H48SR, 200W Half Brick Family
DC/DC Power Modules: 48V in, 1.8V/80A out
The Delphi Series H48SR Half 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 200 watts of
power or up to 80A 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 H48SR converters are capable of providing much 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.
