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.
