PRODUCT OF THE WEEK: SOSA Aligned Power Supply from Vicor
Sponsored StoryMarch 02, 2026
This week’s product, the SOSA Power Supply from Vicor, is aligned with the Open Group Sensor Open Systems Architecture, or SOSA, Technical Standard. The commercial off-the-shelf (COTS) device is designed for 3U OpenVPX systems that are aligned to the SOSA approach and is targeted for use in avionics, shipboard applications, and other defense applications.
As many as four power supplies can be paralleled to increase output power capability of +12V main and +3.3V auxiliary outputs with proprietary wireless current-sharing. The need for conventional current‑share pins is eliminated and current-share accuracy is ±2A.
The module leverages proprietary Vicor technology to enable high efficiency and power density for this rugged, conduction-cooled power supply.
