The air-cooled 3U nine-slot D2D chassis from Curtiss-Wright comes in a 3/4 ATR tall long format. The Hybricon D2D-34TLA enclosure enables a system integrator to use the same COTS enclosure throughout the complete program lifecycle, from development to demonstration to deployment. The OpenVPX enclosure eliminates the need to design a custom backplane, speeding the commencement of system design. The chassis uses a standard COTS backplane and I/O cabling, MIL 28V-input power, and an industrial-grade fan. When the application is ready for demonstration or deployment, the standard backplane and cables of the unit may be replaced with a custom backplane and I/O panel, and the fans may be upgraded to MIL grade units.
