APPLICATIONS
Distributed Power Architectures
Workstations
EDP Equipment
Telecommunications
The VSX40 Series are dual output
converters with a 36-75V input. The
industry quarter-pak size of 2.3" x 1.5"
x 0.5" coupled with 89% efficiency is an
industry high-density breakthrough.
These converters utilize Vx high density
technology. This technology has been
featured in our highly efficient VKP and
VKA series now successfully in use
worldwide. The very high 89%
efficiency minimizes the requirement for

heat-sinking and the low output ripple
minimizes the need for additional
filtering. For maximum flexibility,
power can be traded between outputs as
required. The VSX40 series feature
virtually all of the options required by
design engineers but not at the
competition’s typical additional price
for each option. This multitude of
features are standard on the VSX40
series.
