The GX5295 is high performance PXI instrument and depending on specific operating conditions, the board can require significant power and cooling. The table below provides a summary of the GX5295’s power requirements for static and dynamic operating conditions. Specific power requirements and dissipation will be dependent on the number of active digital channels and data rate. If using the board’s PMU capabilities only, the board’s power consumption is similar to the idle / initialized operating condition.

Note: All PXI chassis are required to supply at least 30 watts of power per slot. For high performance applications or multiple card configurations, a PXI chassis needs to be selected that has adequate DC power and cooling capabilities such as the Marvin Test Solutions GX7300 or GX7600. A PXI peripheral slot can deliver 60 watts however; you must ensure that the PXI chassis has adequate DC power for your specific application and configuration.

Caution - The GX5295 can dissipate significant heat. It is essential that the PXI chassis’ cooling system not be restricted and that all blank PXI slots be closed. Any air flow restrictions such as dirty air filters or blocked ventilation openings can result in excessive heat rise within the chassis and damage to the GX5295. |
