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.
