Delphi Series Q48SK11049 Quarter Brick Family DC/DC Power Modules 48V In, 11V/49A Out The Delphi Series Q48SK11049, Quarter Brick, single output, isolated DC/DC converters are the latest offering from a world leader in power systems technology and manufacturing Delta Electronics, Inc. The Q48SK11049 series product is a regulated Bus converter at a certain Vin, and the Vo will be regulated along with Vin with a fixed proportion It can operate with 49A max output current from 38V to 58V Vin in an industry standard quarter brick footprint. At 58V input, the module provides up to 660W output power. Typical efficiency for the 48V Vin, 11V/49A output is 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.
