The MVA-FIAM5B is a DC front-end module
that provides EMI filtering and transient
protection. The MVA-FIAM5B enables
designers using Vicor’s Maxi, Mini, Micro
Series 24 V converters or VIPAC Arrays to
meet conducted emission / conducted
susceptibility per MIL-STD-461E; and input
transients per MIL-STD-704E/F. The MVA-
FIAM9 accepts an input voltage of 14 – 36
Vdc and delivers output power up to 560 W.
MVA-FIAM5B is mounted on a 4.69" x
3.62" coldplate with a height of 0.81” and
convenient input and output connectors.

Note:
The MVA-FIAM5BH and MVA-FIAM5BM are delivered with the On / Off control already configured as On using a 0 Ohm resistor on
the underside of the output connector board. The MVA-FIAM5BH-C and MVA-FIAM5BM-C are delivered without the 0 Ohm resistor
installed, allowing for user control of the On / Off functionality.
