Delphi Series V48SB, 1/16th Brick Bus Converter
DC/DC Power Modules: 48Vin, 150W, 12Vo or 9.6Vo
OPTIONS
th
The Delphi Series V48SB, 1/16 Brick sized, 48V input, single
output, fixed ratio bus converters are the latest offering from a world
leader in power systems technology and manufacturing — Delta
Electronics, Inc. This product features an input voltage range of 38V to
55V and provides up to 150 watts of power or up to 16A (9.6Vo) o
f
output current in an industry standard footprint and pinout. Both the 5:1
(9.6V) and 4:1 (12V) bus converters operate with constant output curren
t
from 38V to 55V input. Typical full load efficiency for both modules a
t
48Vin is up to 95.2%. This product represents the next generation o
f
design technology that supports the intermediate bus architecture to
power multiple downstream non-isolated point-of-load (POL) converters.
With creative design technology and optimization of componen
t
placement, these converters possess outstanding electrical and thermal
performance, as well as extremely high reliability under stressful
operating conditions. All modules carry a full set of international safet
y
approvals.
