The Seasonic Active PFC F3 Power Supply delivers stable, efficient power for National Instruments PXI-1031 and PXI-1033 chassis. Built with Active Power Factor Correction, this supply optimizes AC input utilization across global voltage standards and maintains operation through frequency variations common in industrial and field environments. The unit operates from 90–264 VAC at 47–63 Hz, achieving greater than 70% efficiency at full load. Temperature-controlled fan management keeps acoustic emissions as low as 35 dBA, meeting ISO 7779 standards at the operator position. Designed for 3U PXI and CompactPCI module integration, the power supply withstands operational shock to 30 g peak and maintains performance across 0–50 °C and 10–90% noncondensing humidity.
