Products Highlights
The 2nd Generation IAM48 is a
component level, DC input front-end
designed to occupy minimum board
space while providing maximum
transient protection for today’s
sophisticated electrical systems. The
IAM48, in combination with Vicor’s
48V input 2nd Generation DC-DC
converters, provides a highly efficient,
high density power system with
outputs from 1 to 100Vdc.
When the IAM48 is used with the
Vicor FM48-FiltMod, the
combination meets the conducted
EMI specifications of Telcordia,
FCC and European Norms.
