Delphi Series Q48DB, 65W Quarter Brick Dual Outputwww.DataSheet4U.com
DC/DC Power Modules: 48V in, ±12V, 2.7A 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 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.
