The VKA100xSC Series DC/DC con-
verters present an economical and
practical solution for distributed power
system architectures which require
high power density and ef?ciency while
maintaining system modularity and
upgradeability. With the ability to oper-
ate 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 today’s
telecommunication and electronic data
processing applications. The output is
fully isolated from the input, allowing
for a variety of polarity and grounding
con?gurations.
The VKA100xSC’s proprietary con-
trol circuitry responds to 50-100% load
steps in 100mSeconds to within 1%
nominal Vout.
The patented ?xed frequency
architecture combined with surface
mount technology results in a compact,
ef?cient and reliable solution to DC/
DC conversion requirements. Safety Per
UL1950, EN 60950 and CSA 22.2 #234
