The AP Labs FS-5968 is a ³/₄-short ATR forced-air conduction cooled chassis designed for use in Vetronics and Space environments.  Specifically, the FS-5968 chassis meets the environmental requirements of MIL-E-5400 for Class 1 equipment designed to withstand extremes of temperature, vibration, shock, salt spray, sand and chemical exposure while maintaining a sealed environment.

Mounting & Cooling
The FS-5965 is designed to be hard-mounted to a cold-plate.  The base structure of the chassis matches the physical outline limits defined in the ARINC 404A^TM  specification for a ³/₄-short ATR box.  The  enclosure side walls are strengthened with gussets, extending beyond the ³/₄ ATR  dimensions, supporting the hard-mounting cold-plate cooling approach.  This eliminates both the conventional shock tray and any required integral air cooling.  The FS-5968 provides a secure enclosure for conduction cooled cards over a wide mounting surface temperature range.  With a 0^oC cold plate, 70% PSU efficiency and uniform power dissipation amongst all card slots, the FS-5968 can dissipate up to 250 Watts.
