Delphi Series Q48SP, 216W Quarter Brick Family
DC/DC Power Modules: 48V in, 12V/18A out
The Delphi Series Q48SP Quarter Brick, 48V input, 12V 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 216 watts of power or up to 18A of
output current in an industry standard footprint. 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 Q48SP Delphi Series converters meet all
safety requirements with basic insulation.
