Categories: ,

The Tech Square PXES-2780 is an 18-slot PXI Express chassis, compliant with PXI Express and cPCI Express specifications and offering one system slot, one system timing slot, and ten hybrid peripheral slots, and six PXI Express peripheral slots for a wide variety of testing and measurement applications requiring enhanced bandwidth. The PXES-2780 provides a configurable PCIe switch fabric and is configurable in two-link, and four-link PXI express deployments, with 8 GB/s system bandwidth and up to 4 GB/s slot bandwidth for dedicated peripheral slots, thanks to PCIe gen2 signaling technology. The PXES-2780 implements a smart system monitoring controller, reporting full chassis status, including fan speed, system voltages, and internal temperature. Equipped with an industrial-grade AC power supply, the PXES-2780 provides 800 W under 55°C, and superior cooling capacity, from three 120 mm fans on the rear of the chassis, and two BNC connectors for 10 MHz clock input/output on the rear panel to increase chassis flexibility, enabling synchronization with supplementary devices. All in all, PXES-2780 is a superior PXI Express platform choice for testing and measurement requirements.


Configurable PCIe Switch Fabric
The PCIe switch fabric of PXES-2780 can be configured in four-link, or two-link, users can configure it depending on the different application.

Innovative Cooling
The Tech Square PXES-2780 features an innovative heat dissipation solution, with three 185.9CFM cooling fans in the rear section of the chassis drawing cool air through lower apertures, then exhausting through the back. This design normalizes airflow for each PXI slot, delivering exceptional cooling. When installed in a rack, the cooling design minimizes the intake of hot air from the rear side, separating airflow for modules and power supplies, while isolating source (fan) noise from modules and maintaining a steady internal temperature.

Intelligent Chassis Management
The PXES-2780″s built-in system monitoring controller monitors and manages full chassis status, including internal temperature, fan speed, and DC voltages, with monitored data accessible with the embedded controller or remote PC via a standard RS-232 connector.

Hybrid Peripheral Slot Design
The Tech Square PXES-2780 features 10 hybrid peripheral slots, preserving backward compatibility to accept PXIe/PXI/cPCIe/cPCI modules, providing maximum flexibility in PXI and PXI Express module slot replacement, reducing the costs of a system upgrade.
