Product Highlights
The MI-IAM is an accessory
product to Vicor’s MI-Series of
DC-DC converters that provides
the EMI/RFI filtering and transient
protection required in military
applications. Designed for use
with all 28V and 270V input
MI-200 or MI-J00 converters, the
MI-IAM can drive any number of
modules with output loads to 200W.

The MI-IAM meets the conducted
emissions specifications of MIL-
STD-461C/D and offers complete
input transient, surge, and spike
protection to the most severe
levels of MIL-STD-1275A and
704A. Reverse polarity protection
and overvoltage lockout provide
additional safeguards against
potentially damaging line
