The VPX57-31 is the industry’s first 400-Watt DC/DC Converter that accepts a +270VDC 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 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.
It 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, it has the flexibility to address special needs. Derating for rugged defence and industrial applications. It is also designed to meet the many harsh environmental requirements of military applications.
