Delphi Series Q48DB, 65W Quarter Brick Dual Output

DC/DC Power Modules: 48V in, ±12V Output

The Delphi Series Q48DB Quarter Brick, 48V input, positive and negative

bipolar dual output, and isolated DC/DC converters are the latest offering

from a world leader in power system and technology and manufacturing ―

Delta Electronics, Inc. This product family provides positive and negative

bipolar output (output voltage is 12V) and up to 65 watts of power in an

industry standard quarter brick package size. Both output channels can be

used independently. With creative design technology and optimization o

component placement, these converters possess outstanding electrical

and thermal performance, as well as extremely high reliability under highl

stressful operating conditions.

ll models are fully protected from

abnormal input/output voltage, current, and temperature conditions. The

Delphi Series converters meet all safety requirements with basic

insulation.
