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 b10% 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.
