Description
constant over the entire input voltage range. Two input to
output isolation test voltage categories and two tempera-
ture ranges are available.
This series of DC-DC converters has been developed for
powering electronic circuits, e.g. telephone system compo-
nents, control modules and small appliances.They are also
suitable for applications with variable input voltages or with
input transients. The converters feature high efficiency,
high reliability, and good dynamic response to load
changes and at start-up. Efficiency is high and practically
All modules are manufactured according to ISO 9001.
Case: DIL 24 package, grey coloured plastics, self cooling
(free air convection).
