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
conditions. High power arrays can
be configured using the expansion
port capability of the MI-IAM.
