150-Watt DC/DC Converter, 6U VME/cPCI

Model DC/DC 55PQ2

150-Watt DC/DC Converter, 6U VME/cPCI

NAI’s 55PQ2 is a 150-Watt DC/DC Converter that plugs directly into a standard 6U VME chassis with an 0.8” slot. It is conduction-cooled through the card edge/wedgelock. This switching power supply accepts +28 VDC input, provides up to 5 outputs at 150 Watts, and addresses the power supply needs of both VME and cPCI systems. An outboard microcontroller allows for design flexibility.

Standard features include continuous Background Built-in Test (BIT); remote error sensing and remote turn on/off; shutdown vibration testing; and protection against transients, over-voltage, and short circuits. Options such as current share, temperature monitoring, 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.
