700-Watt AC/DC Power Converter, 6U VPX

Model AC/DC VPX56-6

700-Watt AC/DC Power Converter, 6U VPX

NAI’s VPX56-6 is a 700-Watt AC/DC Power Converter which accepts either a 3Ø 115VAC L-N inputs or a +270 VDC input.  It plugs directly into a standard 6U 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 VPX56-6 power converter is conduction-cooled through the card edge/wedgelock. It accepts 3Ø AC or +270 VDC input and provides six outputs and I/O at up to 700 Watts and supports a variety of standard features, including continuous Background Built-in-Test (BIT); remote error sensing; and protection against transients, overvoltage, overcurrent, and short circuits. With its intelligent design, the VPX56-6 also has the flexibility to address special needs. Optional current share is available on main outputs.

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

This Product is not available for new designs - Existing applications only.
