Delphi Series E48SB, 240W Eighth Brick Bus Converter   

DC/DC Power Modules: 48Vin, 12V/20A out

 

 
Delta Electronics, Inc., a world leader in power systems technology and 
manufacturing, has introduced the E48SB, eighth brick sized 240W 
bus converter, into their Delphi Series of board mounted DC/DC power 
converters to support the intermediate bus architecture to power multiple 
downstream non-isolated point-of-load (POL) converters. The E48SB 
product family features an input voltage of 38V to 55V, and provides up to 
240W (9.6V and above) of power in an industry standard eighth brick 
footprint. Typical efficiency of 12V module is 96.3%. With optimized 
component placement, creative design topology, and numerous patented 
technologies, the E48SB bus converters deliver outstanding electrical 
and thermal performance. An optional heatsink is available for harsh 
thermal requirements.
