Product Highlights

The MI-IAM is an accessory product to Vicor’s

MI-Series of DC-DC converters that provides EMI

filtering and transient protection. Designed for use

with all 28 V and 270 V input MI-200 or MI-J00

converters, the MI-IAM can drive any number of

modules with output loads to 200 W.

The MI-IAM meets the conducted emissions

specifications of MIL-STD-461C/D/E and offers

complete input transient, surge, and spike protection

to the most severe levels of MIL-STD-1275,

MIL-STD-704 and DO-160. 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.
