3U VPX CMFF / SAVE COMPLIANT CHASSISALIGNED TO SOSA™ AND CMOSS

DESCRIPTION
The Elma CMFF Chassis is an off-the-shelf 3U SOSA and CMOS
alligned configurable and deployable chassis solution designed for
ground vehicles and ground combat environments. It is intended
for Integrated Command, Control, Computers, Cyber, Intelligence,
Surveillance, and Reconnaissance (C5ISR) and designed for ground
vehicle applications. The chassis meets the size, weight, power,
and connector, and electrical interface requirements outlined by the
Standard A-Kit Vehicle Envelope (SAVE)
The Chassis is compliant to CMOSS and aligned with SOSA
Technical Standard. This mission-ready chassis comes standard with a
7 slot backplane ready to accept SOSA aligned plug-in cards (PICs)
and VITA 62 power supply and is an ideal way to rapidly integrate a
deployable platform. The chassis ships with the backplane, a
chassis manager, a hold-up module, and a VITA 62 plug-in power
supply. All are SOSA aligned. A key feature is the USB-based mainte
nance port aggregator for simplified servicing.
The all-aluminum chassis incorporates military-grade components like
MIL- STD-38999 connectors, line filter, on/off and reset switches,
LEDs, circuit breakers, etc. It is EMC shielded to MIL-STD-461E. The
cooling fan is a military-grade, high-altitude fan that can operate under
extremely harsh temperature conditions. Custom options such as
different backplanes, dual power supplies, and different cabling are
available from the factory upon request.
