Delphi Series H48SV, 150W Half Brick Family
DC/DC Power Modules: 48V in, 5V/20A out
The Delphi Series H48SV Half Brick, 48V input, single output, isolated
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 150 watts of power or 40A of output current
(3.3V model) in an industry standard footprint. This product family comes
with standard positive trimming method and utilizes standard trim value.
It also comes with output trimming range between +10% to –20%. All
models are fully protected from abnormal input/output voltage, current,
and temperature conditions. The Delphi Series converters meet all
safety requirements with basic insulation.
