MIL-COTS VPX Power Systems

Standard VITA 62 and SOSA Power Systems

Leveraging the benefits of our DC-DC converter technology and modular building blocks, Vicor offers a range of standard and modified-standard VPX power systems for use in compact enclosures and space-constrained airborne and vehicle environments where temperature, shock and vibration conditions can be severe. There are 3U and 6U models available which are compliant to the VITA 62 standard, and we have SOSA-aligned products in development. The current products are available in 270Vin and 28Vin, and are capable of providing one to six user-configurable outputs, with voltages from 2VDC to 48VDC. Standard features such as wide output trimming / programming, current limiting, remote sense, reverse polarity protection, logic enable / disable are available. Products meet relevant standards, including MIL-STD-810F environments, MIL-STD-461E EMI, MIL-STD-1275A B and D, MIL-STD-704D/E/F transient compliance and MIL-STD-1399A, shock and vibration in conformance with MIL-STD-901D.
