Delphi Series H48SV, 150W Half Brick Family
DC/DC Power Modules: 48V in, 5V/30A out
The Delphi Series H48SV Half Brick, 48V input, single output, isolated
DC/DC converters are the offering from a world leader in power systems
technology and manufacturing — Delta Electronics, Inc. This product
family provides an extremely cost effective solution for up to 150 watts of
power or 40A of output current (3.3V model) in an industry standard
footprint. The H48SV series has an insulated metal baseplate
construction and all the power dissipation components are mounted
directly onto this insulated metal baseplate. This provides a great
thermal management of the module and a superior thermal interface to a
heatsink. With creative design technology and optimization of
component placement, these converters possess outstanding electrical
and thermal performance, as well as extremely high reliability under
highly stressful operating conditions. All H48SV models are fully
protected from abnormal input/output voltage, current, and temperature
conditions. The Delphi H48SV Series converters meet all safety
requirements with basic insulation.
