Delphi Series E48SP Eighth Brick Family DC/DC Power Modules: 48V in, 12V/20A out OPTIONS The Delphi Series E48SP, 36~75V input, Eighth Brick, single output, Positive On/Off logic isolated DC/DC converters are the latest offering from a world leader in Short pin lengths available power systems technology and manufacturing Delta Electronics, Latched over voltage protection Inc. The E48SP product provides up to 240 watts of power in an industry standard footprint and pinout. The E48SP converter operates from an input voltage of 36V to 75V. Efficiency is 94.5% for the 12V output at full load. With creative design technology and op timization 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 APPLICATIONS temperature conditions. The Delphi Series converters meet all safety Telecom/DataCom requirements with basic insulation.
