SOSA Aligned Power Supplies

The Vicor SOSA-aligned power supply is a COTs power supply that is designed for 3U Open VPX systems that are developed to the SOSA standard. The module utilizes Vicor proprietary technology to enable high efficiency and power density for this highly rugged, conduction-cooled model.

Up to four power supplies can be paralleled to increase output power capability of +12V main and +3.3V auxiliary outputs with proprietary wireless current sharing. Need for conventional current‑share pins are eliminated. Current share accuracy is ±2A.
