Filter Input Attenuator Module
Shown actual size: 2.28 x 2.2 x 0.5 in 57,9 x 55,9 x 12,7 mm
Product Highlights
The FIAM is a DC front-end module providing transient protection, inrush current limiting and Class B EMI filtering in a Minisize package. The FIAM enables designers using Vicor 2nd Generation, 48Vin DC-DC converters to meet the transient immunity and EMI requirements of Bellcore, FCC, ETSI and European Norms while protecting system hardware from inrush current. The FIAM accepts an input voltage of 36-76Vdc, is available in 10 or 20A versions and provides reverse polarity protection and remote on/off. FIAM 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.
