North Atlantic Industriesí (NAI) VPX57-31 is a 400-watt DC/DC converter that accepts†a +270 VDC input and plugs directly into a standard 3U VPX chassis with a VITA 62 1.0-inch power supply slot. This off-the-shelf solution for VITA 46.0 and VITA 65 systems is compatible with VPX specifications; supports all VITA standard I/O, signals, and features; and conforms to the VITA 62 mechanical and electrical requirements for modular power supplies. The VPX57-31 switching power supply is conduction-cooled through the card edge/wedgelock. It accepts +270 VDC input voltage and provides six outputs (per VITA 62) at up to 400 watts. The VPX57-31 can be used either as a single-stage module or a back-end module in a multiple power supply configuration. It supports a variety of standard features, including continuous background built-in-test (BIT); user programmability; I2C communication; remote error sensing; current share; and protection against transients, overvoltage, overcurrent, and short circuits. The VPX57-31 also is flexible enough to accommodate special needs. The design is aimed at meeting the many harsh†environmental requirements of military applications.
