Vicor Corp. announced two new 500W additions to its family of Filtered Input Attenuator Modules (FIAMs) for railway applications. The new FIAM110 and FIAM072 provide protection for on-board equipment and systems against the effects of power-line transients, EMI (electromagnetic interference) and excessive in-rush currents.
On-board power supplies in rail environments are subject to severe levels of transients and noise that can be disruptive or damaging to systems such as lighting, communications, and information displays unless properly filtered. The FIAM110 and FIAM072 meet EN50121-3-2 for EMI filtering and EN50155/EN50121-3-2 for transient protection – requirements that are crucial for rail applications. In addition, the FIAM110 and FIAM072 conform to RIA 12 surge and transient requirements and are qualified for demanding environmental standards.
The FIAM072 accepts an input voltage of 43-110Vdc and the FIAM110 accepts an input voltage of 66-154Vdc. Both provide up to 500W of output power, with efficiencies up to 98%, and remote on/off control. The FIAM110 and FIAM072 modules are in the industry-standard ’half-brick’ footprint measuring 2.28 x 2.2 x 0.5 inches, which is ideal for space constrained designs, and are compatible with the Mini, Micro and Maxi or VI/VE-200 and VI/VE-J00 dc-dc converters from Vicor’s brick product portfolio.
The FIAM110 and FIAM72 are priced at $71.00 for OEM quantities and are available now.
