Delphi Series E24SR, 66W Eighth Brick Family DC/DC Power Modules 24V in, 6.5V/8A out

The Delphi Series E24SR Eighth Brick, 24V 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 is available in either a through-hole or surface-mounted package and provides up to 66 watts of power or 20A of output current 3.3V and below in an industry standard footprint and pinout. The E24SR converter operates from an input voltage of 18V to 36V and is available in output voltages from 3.3V to 12V. Efficiency for the 6.5V output is at 8A 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.
