Astronics / EADS / Racal 1264B 6-Slot, C-Size VXI Mainframe, Benchtop

The Astronics/EADS/Racal 1264B is a 6-slot, C-size VXI mainframe engineered for benchtop test and measurement systems. This lightweight chassis accommodates VXI modules in a compact form factor while delivering 500 W of usable power from an 800 W supply with auto-ranging input (115 VAC ±10% / 230 VAC ±10%). The modular power supply assembly includes wireless interconnect and comprehensive protection against over-voltage, over-temperature, over-current, and short-circuit faults with status indication across all seven rails.
