DDU cabinet

Data Distribution Unit

Cabinets currently operational on various submarines

As part of an export program, EPCOTS has realized the mechanical and electrical wiring design and production of the DDU cabinet for Safran. This equipment is part of the navigation system of a SSK submarine. It is linked to different kind of navigation sensors, converts the signals and provides the position of the submarine. These functions are really critical which requires use of adapted products. In this context, the EPCOTS’ ability to design reliable and rugged equipment was a really convincing fact for SAFRAN. Besides, due to a very constraining space inside the submarine, the EPCOTS’ capability to design narrower cabinets (less than 19’’) was another reason of the SAFRAN’s choice.
After a design (including mechanical and some electronic parts) and qualification phase, EPCOTS has provided its customer with series units reaching the SAFRAN’s expectations and which are now sea proven.

Internal wiring and integration performed by EPCOTS
Equipped with shock absorbers to withstand high levels of shocks
Specific width (<19’’) to fit the dimensional constraints of the platform
Racks equipped with “zero insertion force” connectors to ease their replacement
