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.
