Summary
The IMP 3 series of DC-DC converters have been devel-
oped for powering commercial type of electronic circuits,
e.g. telephone systems components, industrial controllers
and small appliances, featuring short-circuit protection and
input to output isolation. With a good efficiency as well as
good dynamic response to load changes and at start-up,
the IMP 3 series is the best solution for applications where
high reliability and high performance for a low price is re-
quired.
