Vicor Iintroduces 10kW Power Tablet AC-DC converter

Vicor has announced a 3-phase, AC-DC converter module (“RFM”), capable of delivering 10kW of regulated 48VDC in a power tablet configuration measuring 9.4 x 5.9 x 0.6in (24 x 15 x 1.5cm).

The RFM provides a power-factor-corrected, regulated, and isolated DC output with integrated filtering and built-in fault protection for redundant operation and can be configured to accept worldwide 3-phase AC mains from 200 to 480VAC.

Its low-profile power tablet design means that the RFM enables much improved power density and thermal management flexibility. For example, four RFMs in parallel, including input-disconnect circuitry, rectification and hold-up energy storage at 48V, can supply 40kW of power within 1U of rack space. The RFM package provides thermal management for advanced cooling, including liquid cooling, of high-power server racks for demanding HPC and AI inference and learning applications.

48V (including 54VDC) distribution is the emerging standard in high-power racks utilising smaller-gauge wiring, and achieving substantially lower distribution losses, than legacy 12VDC distribution. In combination with Vicor 48V Power-on-Package (“PoP”) and 48V Direct-to-PoL solutions, the RFM enables dense and efficient end-to-end power system solutions, from 3-phase AC to sub-1V AI processors at the point-of-load.

The 10kW power tablet RFM is the first in a new series of single and 3-phase AC-DC modules featuring power outputs from 150W to 15kW.
