VITA48.4 Liquid Flow Through Development Chassis

Elma Electronic’s newest OpenVPX development platform is designed to accommodates board requiring VITA 48.4 LFT (Liquid Flow-Through) cooling. The standard establishes the mechanical design
interface, outline and mounting requirements for a 6U VPX liquid-flow-through cooled plug-in module within associated sub-racks. The connector layout remains common with VITA 46. This plug-in module uses liquid flowing through an integral heatsink of the module for cooling the electronic components and circuit boards. The quick disconnect coupling assemblies allow fluidic coupling to the chassis manifold. Intended for proof of concept testing and development tasks, this self-contained VITA 48.4 LFT platform is designed to accept up to five 6U VPX plug-in modules on a 1” pitch, and either a built-in power supply or a plug-in VITA 62 power module. The liquid-to-air heat exchanger provides the required fluid for cooling, and a flow indicator shows whether the fluid is circulating. The system can be adapted to any slot count and module pitches.



  • Accepts up 6 OpenVPX modules
  • Built-in plug-in VITA 62 power module option
  • Built in heat exchanger
  • Flow indicator shows fluid is circulating
  • Extensible design for adaptation to higher or lower slot counts
