The National Instruments 778932-01 PXI Chassis is a highly versatile 4-slot universal AC chassis designed for environments where low acoustic noise is a priority, such as offices, laboratories, and educational institutions. As part of the PXI-1031 model family, this chassis provides a universal AC input, accommodating voltage ranges from 100 to 240 VAC and operating frequencies of 47 to 63 Hz. It features an intelligent cooling system with temperature-controlled fan speeds, significantly minimizing noise levels while ensuring optimal thermal conditions for the integrated modules. Each slot in the chassis offers a cooling capacity of 25 W, thereby supporting effective performance during high-demand applications. The front panel is equipped with an On/Off power switch for easy access, while an optional carrying handle enhances portability, making it suitable for mobile applications. The rack-mountable design enables seamless integration into existing setups or equipment racks. Compatibility is a key advantage of the 778932-01, as it supports standard CompactPCI products as well as 5 V and universal PXI-compatible modules, significantly reducing potential compatibility issues in complex PXI systems. Efficient forced air circulation enhances the chassis’s cooling capabilities, with intake at the front and exhaust at the rear, ensuring effective heat dissipation from the modules.
