OPTIONS
Processing Power Inteface Modules
5.0V LED Power disable or enable
The Delphi DIM series, dual redundant input power processing
isolated DC/DC converter is the latest offering from a world leader in
power system technology and manufacturing Delta Electronics, Inc.
This product family provides up to 500-1100 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
redu ndant, hot swappable 48Vdc power distribution with EMI filtering
and inrush current limiting for an ATCA (Advanced
Telecommunications Computing Architecture) or other telecom
boa rds. In addition to processing the dual redundant 48V bus, the DIM
APPLICATIONS
module also provides isolated auxiliary 3.3V (3.6A), and/or 5V
Telecom / Datacom
(150mA) BLUE_LED power for other housekeeping functions. With
Wireless Networks
crea tive design technology and optimization of component placement,
Optical Network Equipment
these converters possess outstanding electrical and thermal
performances, as well as extremely high reliability under highly
Server and Data Storage
stre ssful operating conditions. All models are fully protected from
