Product Highlights
The M-FIAM5 is a DC front-end module
that provides EMI filtering and transient
protection required in military applications.
The M-FIAM5 enables designers using
Vicor 2nd Generation 24V DC-DC converters
to meet conducted emission/conducted
susceptibility per MIL-STD-461E; and
input transients per MIL-STD-704E
1
. The
M-FIAM5 accepts an input voltage of
18-36Vdc and delivers output current
up to 20 Amps.
M-FIAM5 is housed in an industry
standard "half brick" module measuring
2.28" x 2.2" x 0.5" and depending upon
model selected, may be mounted on-board
or in-board for height critical applications.

MIL-STD-704E Transient / Overvoltage Protection
The standard (COTS) 24V input 2nd Generation Converter Modules may be used in Military 28 volt applications. The
M-FIAM5 provides compliance to MIL-STD-461E conducted emissions and susceptibility standards. Additional circuitry,
as illustrated in the accompanying schematic (see Fig. 1), provides compliance to the MIL-STD-704E transient
overvoltage specification. The 24V input modules employ undervoltage and overvoltage protection. These converters,
shut down if the input falls below 18V or rises to 36V or above.18V is consistent with the MIL-STD-704E specification,
but the standard also requires uninterrupted performance in the event of an input voltage transient to 50V for a period
of 12.5 millisec. The above referenced circuit clamps the input voltage, in the event that it exceeds 32V, as illustrated in
figure 2. This performance prevents the converter from shutting down, thus meeting the transient overvoltage
specification of MIL- STD-704E.
