The Delphi Series Q48SB, 48V input, single output, quarter brick, 500W 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.
The Q48SB9R6 (5:1) operates from a nominal 48V input and provides up to 500W of power or up to 63A (@ 38Vin) of output current in an industry standard quarter brick footprint.
The Q48SB 5:1 bus converter operates with 500W constant output power, hence when input voltage drops, the output current will increase accordingly.
Typical efficiency for the 9.
6V/50A output is 96.
8%.
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.
