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.
