Delphi Series DIM, 300W Dual Input Power Processing DC/DC Power Modules OPTIONS The Delphi DIM series, 300W dual redundant input power processing 3.3V management Power 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 APPLICATIONS 3.3V (8W), and/or 5V (100mA) BLUE LED power for other Telecom / Datacom housekeeping functions. With creative design technology and Wireless Networks optimization of component placement, these converters possess Optical Network Equipment outstanding electrical and thermal performances, as well as extremely Server and Data Storage high reliability under highly stressful operating conditions. All models Industrial / Testing Equipment are fully protected from abnormal input/output voltage, current, and temperature conditions. The Delphi DIM series converters meet all safety requirements with basic insulation.
