DESCRIPTION
The VKA150MS 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 33 to 75 volts, these modules are
ideal for use in battery backup applications common in
todays' telecommunication and electronic data process-
ing 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 surface mount technology results in a compact,
efficient and reliable solution to DC/DC conversion
requirements.
