NAI’s VPX55-3 is a 400-Watt DC/DC Converter that plugs directly into a standard 3U VPX chassis with a 0.8” slot. It is conduction-cooled through the card edge/wedgelock. This programmable, switching power supply can be used either as a single-stage module or a back-end module in a multiple power supply configuration. It accepts +28 VDC input voltage and provides six outputs at up to 300W (standard).
Standard features include continuous Background Built-in-Test (BIT); remote error sensing; and protection against transients, over-voltage, over-current, and short-circuits. Options such as 400W output power, reverse polarity protection (300W version only), and current share are available.
This COTS converter 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.
