FIAM – Filter Input Attenuator Module

DC Front-End Module providing Transient Protection, Inrush Current Limiting and EMI Filtering

Description

The FIAM is a DC front-end module providing transient protection, inrush current limiting and Class A EMI filtering in a mini-sized package. The FIAM enables designers using Vicor’s 48 Vin Maxi, Mini and Micro series, 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 – 76 Vdc, is available in 10 or 20 A 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 onboard or inboard for height critical applications.
