The VKA50xS Series DC/DC
converters present an economical and
practical solution for distributed
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'
telecommunication and electronic
data processing applications. The
output is fully isolated from the
input, allowing for a variety of
polarity and grounding configura-
tions.
The VKA50xS's proprietary
control circuitry responds to 50-100%
load steps in 100
µSeconds to within
1% nominal Vout.
The patented fixed frequency
architecture combined with surface
mount technology results in a com-
pact, efficient and reliable solution to
DC/DC conversion requirements.
Safety per UL1950, EN 60950 and
CSA 22.2 #234
