The National Instruments 778647-01 is a high-performance Replacement Power Supply and Fan Shuttle, specifically engineered for compatibility with the PXI-1044 and PXI-1045 Chassis. This modular design facilitates quick replacement of failed units, significantly minimizing downtime, with a Mean Time To Repair (MTTR) of less than five minutes. The unit integrates both cooling fans and fan-control circuits, featuring a fan-speed selector switch located on the rear panel to optimize cooling performance while allowing for quieter operation. Users can select between "HIGH" for maximum cooling efficiency or "AUTO," where fan speed adjusts based on air intake temperature.

The 778647-01 includes essential circuitry for monitoring power supply status via a front-panel LED indicator that alerts users to power supply failures. It operates on universal AC input, accommodating voltages ranging from 100–240 VAC and frequencies of 50/60 Hz, with operational ranges of 90–264 VAC and 47–63 Hz under load conditions. The device features a robust input current rating of 10–5 A, protected by a 12 A circuit breaker to prevent overcurrent damage. Main power is connected through an AC power cable, and a 9-Pin D-SUB connector is present on the rear panel for additional connectivity. The internal DC outputs are safeguarded against overload and short circuits through an automatic recovery feature. Mounting is straightforward, utilizing ten screws, which can be removed with a number one Phillips screwdriver, and the shuttle is equipped with convenient rear handles for easy removal.
