The Astronics / EADS / Racal 1264C is a 6-slot C-size VXI mainframe for test and measurement applications in laboratory and field environments. This modular chassis delivers 800 W available power (500 W usable) through a wireless interconnect power supply system with real-time monitoring across all seven rails. A pressurized plenum cooling architecture with integral slot blockers maintains even airflow distribution, while recessed module positioning protects connectors and cable loops. The platform operates from 0 °C to 50 °C, measures 16.7 × 8.7 × 21.3 inches (H×W×D), and weighs 27 lbs.
