Delphi Series H48SV, 150W Half Brick Family
DC/DC Power Modules: 48V in, 5V/10A 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.
