The Nova Integration Solutions 3000 Series consists of a family of custom and standard ATR Chassis.  They also  support highly rugged and MIL spec applications required by the Defence and Aerospace markets. The Series provides a full set of packaging features.  Ideally suited to meet the demands of high-performance ground-based applications that must operate in difficult environments or by flight vehicles that operate at high altitudes.

Hence, three (3) classes of product are provided. Also they are classified by the type of cooling technology utilised. Standard products exist that can be further customised. The Series 3000 Reference ATR Chassis Design Specifications can be downloaded to include individual data sheets on each product.
