The VKA100xS Series DC/DC
converters present an economical
and practical solution for distrib-
uted power system architectures
which require high power density
and efficiency while maintaining
system modularity and
upgradeability. With the ability to
operate over a wide input voltage
range of 18 to 36 and 33 to 75
volts, these modules are ideal for
use in battery backup applications
common in todays' telecommuni-
cation and electronic data process-
ing applications. The output is
fully isolated from the input,
allowing for a variety of polarity
and grounding configurations.
The VKA100xS's proprietary
control circuitry responds to 50-
100% load steps in 100碌Seconds
to within 1% nominal Vout.
The patented fixed frequency
architecture combined with sur-
face mount technology results in a
compact, efficient and reliable
solution to DC/DC conversion
requirements. Safety Per UL1950,
EN 60950 and CSA 22.2 #234
