NAI’s 55U91-01 is a 600-Watt DC/DC Converter that plugs directly into two card slots in a standard 6U VME chassis. It is conduction-cooled through the card edge/wedgelock. This switching power supply accepts +28 VDC input, provides up to 9 outputs at up to 614 Watts, and addresses the power supply needs of both VME and cPCI systems.
Standard features include continuous Background Built-in Test (BIT); remote error sensing; remote turn on/off; and protection against transients, over-voltage, over-current, short-circuits, and reverse polarity. Options such as current share, power fail warning, and extensive signaling (including ANSI/VITA) are available, and additional options and special units can be ordered.
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.
