The VKA150MS 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 33 to 75 volts, these
modules are ideal for use in
battery backup applications com-
mon in todays' telecommunication
and electronic data processing
applications. The output is fully
isolated from the input, allowing
for a variety of polarity and
grounding configurations.
The VKA150MS'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 approvals per
UL/CUL 1950, EN 60950
