Product Overview:

Model  4103  is  a  versatile  rackmount  chassis  that  has  been  tested  to  MIL-STD-810  shock  and  vibration,  and  designed  to  meet  EMC/EMI  per  MIL-STD-461 EMC.

Its taller sibling — Model 4107 — is used by the U.S. Navy on long-standing programs  such  as  the  OASIS  LSRS  Radar  System  installed  aboard  the  P-3  Orion,  and  Los  Angeles-class  submarines.  The  4103,  installed  on  Naval submarines world wide, features superior torsional strength due to NOVA’s specially designed, heavy-duty wrought aluminum extrusions that  form  the  outer  chassis.  Moreover,  the  extrusions  are  partially  overlapped for superior EMC.

An  internal  chassis  accommodates  the  customer’s  selected  hardware platform,  drives,  and  optional  hot  swap  power  supplies.  Made  from  aluminum  5052-H32,  the  chassis  is  mechanically  suspended  inside  the  main  chassis  using  multi-axis  mounts  that  attenuate  externally  transmitted shock and vibration energy.

Forced-air   convective   cooling   via   high-CFM   fans   in   a   push-pull   configuration provide laminar airflow across system boards at all times, and can be monitored and controlled by NOVA’s System Environmental Monitor  (SEM).  The  intake  fan  tray  is  also  an  LRU  design,  with  a  5  minute MTTR. Air filters located behind EMC compliant mesh inserts are  easily  accessible  and  quick  to  service  or  replace.  The  4103  chassis  is  highly  resistant  to  airborne  dust  and  sand.  Available  in  customer  definable depths, Model 4103 is configurable to accommodate a variety of passive backplane types or motherboards. And rear panel MIL circular connectors may replace COTS connectors.
