VITA actually stands for “VMEbus International Trade Association,” and this working group develops standards specifically with Defense and Aerospace applications in mind. These system specifications describe the technical implementation details for 3U and 6U VPX payload and switch modules, backplane topologies, and chassis products, which provides clear guidance on how to build interoperable computing and communication platforms. One part of these standards, VITA 62, defines the power supply requirements which are highlighted here.
