Rugged VPX Power Supplies

Rugged VPX Power Supplies Overview

NAI offers COTS and Modified COTS power supplies and power converters that plug directly into standard 3U and 6U VPX chassis and are conduction-cooled through the card edge/wedgelock. With their advanced design, these rugged converters accept either +28 VDC input, +270 VDC input or 3-phase, AC input. These off-the-shelf solutions for VITA 46.0 and VITA 65 systems are compatible with VPX specifications; support all VITA standard I/O, signals, and features; and conform to the VITA 62 mechanical and electrical requirements for modular power supplies.

The NAI VPX family of power products include a variety of standard features, including continuous Background Built-in-Test (BIT); remote error sensing; and protection against transients, overvoltage, overcurrent, short circuits and over temperature. These intelligent designs also have the flexibility to address special needs. Optional current share is available on main outputs.
