Application Scenarios
During a naval combat system upgrade,engineers faced frequent system resets due to unstable power delivery in the ship’s VME-based command and control rack.The existing generic power supplies couldn’t handle voltage fluctuations from the vessel’s electrical grid,leading to data corruption and operational downtime.The integration of the VME162PA344SE resolved the issue:its robust AC/DC conversion and triple-output regulation(+5V,+12V,–12V)provided clean,stable power even under harsh marine conditions.With built-in protection against overvoltage,overcurrent,and short circuits,the VME162PA344SE eliminated unexpected shutdowns.This deployment underscores how the VME162PA344SE acts as the silent guardian of mission-critical VME systems—ensuring uninterrupted data flow and system stability in environments where failure is not an option.

Technical Principles and Innovative Values
Innovation Point 1:The VME162PA344SE integrates a universal AC input stage with active power factor correction(PFC),enabling stable operation across global voltage standards(90–264V AC)and reducing harmonic distortion on the power line—critical for compliance in sensitive installations.
Innovation Point 2:Engineered specifically for the VME64 architecture,the VME162PA344SE delivers precisely regulated+5V,+12V,and–12V outputs directly to the backplane,eliminating the need for additional DC/DC converters and minimizing voltage drop across long traces.
Innovation Point 3:With a compact 6U form factor and convection cooling design,the VME162PA344SE fits seamlessly into ruggedized VME chassis without requiring internal fans,enhancing system reliability in dusty or high-vibration environments.
Innovation Point 4:The VME162PA344SE supports N+1 redundancy configurations when used with compatible VME power shelves,allowing hot-swappable replacement and ensuring continuous uptime in critical control systems.
Application Cases and Industry Value
At a European rail signaling test facility,legacy VME systems were experiencing intermittent failures due to aging power supplies unable to maintain clean+5V rails under load.After replacing them with the VME162PA344SE,system stability improved dramatically.Over a six-month trial,zero power-related faults were recorded,even during simulated grid fluctuations.Engineers noted a significant reduction in electromagnetic noise affecting adjacent signal processing modules.The VME162PA344SE not only restored system reliability but also extended the operational life of the entire VME rack,delaying costly hardware overhauls and ensuring compliance with EN 50121(railway EMC)standards.
