Delphi Series DIM, 300W Dual Input Power

Processing DC/DC Power Modules

The Delphi DIM series, 300W dual redundant input power processing

isolated DC/DC converter is the latest offering from a world leader in

power system and technology and manufacturing ― Delta Electronics,

Inc. This product family provides up to 300 watts of power in an industry

standard footprint and pinout. The DIM series is designed to simplify the

task and reduce the board space of implementing dual redundant, hot

swappable 48Vdc power distribution with EMI filtering and inrush

current limiting for an ATCA (Advanced Telecommunications

Computing Architecture)

or other telecom boards. In addition to

processing the dual redundant 48V bus, the DIM module also provides

isolated auxiliary 3.3V or 5V (8W), and/or 5V (100mA) BLUE_LED

power for other housekeeping functions. With creative design

technology and optimization of component placement, these converters

possess outstanding electrical and thermal performances, 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 DIM series converters meet all

safety requirements with basic insulation.
