DC/DC Power Modules: 48V in, 28V/12.5A out
The Delphi Series H48SN 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 350 watts of power in an industry
standard footprint. It provides 91% efficiency for 28V at full load. 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 models are fully protected from abnormal
input/output voltage, current, and temperature conditions. The Delphi
Series converters meet all safety requirements with basic insulation. A
variety of optional heatsinks are available for extended thermal
operation, as well as for use in higher air flow applications: 200 to 400
LFM.
