Delphi Series L48DB, 30W 2”x1.6” Dual Output

DC/DC Power Modules: 48V in, ±12.0V, 1.25A Output

The Delphi Series L48DB, 2”x1.6”, 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 30 watts of power in an industry

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

independently. 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.
