Summary
The IMR 3 serie 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. They are suitable for applications
with standard battery voltages. The IMR 3 converters fea-
ture good efficiency and good dynamic response to load
changes and at start-up. The IMR 3 modules are short-cir-
cuit and no-load proof.
