National Instruments 778662-01 PXI Chassis Replacement Power Supply & Fan Shuttle
The 778662-01 from National Instruments is an integrated power supply and fan shuttle unit designed as a key replacement part for the NI PXI-1042 PXI chassis. As an assembly, this unit is capable of providing both reliable electrical power and adequate thermal management for the overall PXI system so that it is operating at temperatures and voltage levels established by the manufacturer. By incorporating both of these important components into one removable shuttle unit, this design maintains the overall operational integrity of the chassis and ensures consistent performance from the chassis in test and measurement applications.
Specifically designed to support the power needs of the PXI system and to maintain the optimal temperature of its internal components, this replacement part includes a power supply section with 4 different DC outputs (3.3V, 5V, 12V, and -12V). The integrated fan shuttle is a critical component of this unit in terms of cooling; the fan removes excessive heat generated inside the chassis to prevent overheating and thereby maintain the overall reliability of the system. In addition, the cooling capabilities of this unit are especially critical when the system is being operated over extended periods in harsher conditions.
The use of NI 778662-01 provides assurance that the PXI-1042 chassis will continue to operate as intended to support a wide variety of instrumentation modules, such as those required for automated test systems, data acquisition systems, and control systems. As a result, this unit is essential to maintaining the PXI system and extending the chassis's usable life. Consequently, this unit is considered a very important spares component for the maintenance of the PXI system, for engineers and scientists that rely upon their PXI-1042 chassis for precise and reliable performance in laboratory, production or educational environments.
