Le profil extra plat en forme de tablette du module d\u2019alimentation RFM permet une densit\u00e9 de puissance et une flexibilit\u00e9 de la gestion thermique in\u00e9gal\u00e9es. Par exemple, quatre modules RFM en parall\u00e8le, incluant le circuit \u00e9lectronique de d\u00e9connexion des entr\u00e9es, le redressement et le stockage de l\u2019\u00e9nergie sous 48 V, peut fournir 40 kW de puissance dans un emplacement de rack 1U. Le bo\u00eetier extra plat en forme de tablette du module RFM offre d\u2019excellentes performances de gestion thermique pour les syst\u00e8mes de refroidissement avanc\u00e9s, y compris le refroidissement par liquide, de racks de serveurs haute puissance pour les applications exigeantes d\u2019informatique \u00e0 hautes performances (HPC, High Performance Computing), les services d\u2019inf\u00e9rence \u00e0 base d\u2019IA et les applications intelligentes de type \u00ab machine learning \u00bb.<\/p>\n

La distribution 48 V (y compris 54 VDC) est le nouveau standard sur les racks haute puissance utilisant des c\u00e2bles de section plus \u00e9troite, et affichant des pertes de distribution substantiellement moindres par rapport \u00e0 la distribution existante 12 VDC. Associ\u00e9 aux solutions de Vicor Power-on-Package (PoP) 48 V et Direct-to-PoL 48 V, le module RFM permet de constituer des solutions d\u2019alimentation de bout en bout denses et efficaces, depuis le courant alternatif triphas\u00e9 jusqu\u2019aux processeurs IA inf\u00e9rieurs \u00e0 1 V au point de charge.<\/p>\n

Le module RFM Power Tablet 10 kW est le premier \u00e9l\u00e9ment d\u2019une nouvelle gamme de modules AC-DC monophas\u00e9s et triphas\u00e9s dot\u00e9s de sorties d\u2019alimentation de 150 W \u00e0 15 kW.
