The 3U VPX Air Transport Rack

The 3U VPX Air Transport Rack: Lightweight, rugged, superior cooling

The 3U VPX ATR Integrated System provides a highly customizable compute- and Ethernet-based solution offering reduced weight and superior cooling, ideal for small form factor needs such as tracked vehicles and aircraft.

The assembly ships with a 5-Slot VPX backplane that meets all VITA requirements and is ready out of the box for 3U VPX applications. Core i7 processor blades with 8GB of DDR3 memory provide the bulk of the processing power for high-performance, low-power processing. Power is provided by two 28 VDC, 400W power supplies. The system is cooled via 25C ambient convection-over-conduction cooling, providing up to 100W of heat dissipation per slot, and the sealed exterior and lightweight all-aluminum construction make the 3U VPX ATR rugged enough for the harshest computing environments.
