The Keysight/Agilent/HP E8400A VXI Mainframe Power Supply delivers regulated, stable power to modules within VXI (VME eXtensions for Instrumentation) mainframes. This plug-in power supply unit is essential for reliable operation of VXI-based test and measurement systems across laboratory, industrial, and enterprise environments. The E8400A provides 700 W usable power at 40°C and features rear-accessible installation that allows replacement without removing the mainframe from a rack.
Technical Specifications
• Power Output: 700 W usable at 40°C
• AC Input Range: 90 Vac to 264 Vac, 47 Hz to 440 Hz
• Cooling System: Two-speed cooling fan with Variable (automatic) or Full Speed mode selection via front panel switch. Separate dedicated power supply cooling fans provide independent air distribution.
