NAI’s VPX57-31 is the industry's first 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” 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, over-voltage, over-current, and short-circuits. With its intelligent design, the VPX57-31 also has the flexibility to address special needs. Derating for rugged defense and industrial applications. It is also designed to meet the many harsh environmental requirements of military applications.
