NAI VPX55-3 400-Watt DC/DC Converter, 3U VPX

400-Watt DC/DC Converter, 3U VPX

The VPX55-3 is 400-Watt DC/DC Converter that plugs directly into a standard 3U VPX chassis with a VITA 62 0.8” 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 +28 VDC input voltage and provides six outputs 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); remote error sensing; and protection against transients, over-voltage, over-current, and short-circuits. With its intelligent design, it also has the flexibility to address special needs. Optional current share is available.

This COTS converter is specifically designed with NAVMAT component derating for rugged defence and industrial applications. It is also designed to meet the many harsh environmental requirements of military applications.
