The Delphi Series Q48SB, 48V input, single output, vertically 

mounted quarter brick, 240W bus converter is the latest offering from 

a world leader in power systems technology and manufacturing — 

Delta Electronics, Inc. This product family supports intermediate bus 

architectures and powers multiple downstream non-isolated point-of-

load (POL) converters and devices. The Delphi Series Q48SB 

operates from a nominal 48V input and provides up to 240W of 

power or 20A of output current in an industry standard vertically 

mounted quarter brick footprint. Typical efficiency for the 12V/20A 

module is 96%. With optimized component placement, creative 

design topology, and numerous patented technologies, the Q48SB 

bus converter delivers outstanding electrical and thermal 

performance. An optional heatsink is available for harsh thermal 

requirements.
