COTS

                     

Commercial off-the-shelf (COTS) power supplies are manufactured commercially, readily available, and are non-development items.  These power supplies,when ruggedized may be used in harsh environment applications.

 COTS systems are in contrast to custom power supplies,

 systems that are produced entirely and uniquely for the specific application therefore offering potentially large cost and time savings.

Our COTS power supplies are not produced only for the defense market, but they may be widely used in transportation (railway) and industrial systems, thus providing high reliability cost effective systems. 

Our philosophy is first to try to offer COTS products to our customers in order to ensure low unit costs and short time-to-market. When COTS products are not suitable for the systems, we will offer modified-standard products. Only when both COTS and Modified-Standard are not applicable, we will offer custom power supplies.

 

The use of modified-standard products provides our customers with many key benefits:

  1. Low development costs
  2. Low risk
  3. Short development times
  4. Low unit cost


 
cPCI COTS

 

CompactPCI COTS power supplies are ruggedized power supplies, designed to work in harsh environment.

 

More and more military customers are embracing CompactPCI, especially the smaller 3U form-factor.

 

Along with other embedded COTS technologies, CompactPCI is helping military designers to develop small, mobile, powerful electronic systems for lighter-weight and smaller-sized combat vehicles of various kinds, including ground- and air-based, manned and unmanned.

 

Traditional aerospace applications have utilized VME in the past, but some have shifted to conduction-cooled 3U or 6U CompactPCI, either for bandwidth or because of the need for Ethernet traffic. Another reason to shift to cPCI may be the need for PICMG 2.16 compliance for packet switching.

 

Conduction-cooled CompactPCI boards may cost a bit more than air-cooled boards, which are usually deployed in much larger strategic systems such as submarines or large aircraft. But they also make the envelope a good deal smaller, so the whole subsystem can fit into a large number of applications in harsh and severe environments.

 

Especially in new designs, CompactPCI is winning a place on the bill of materials. Because of the technology available, the level of integration due to newer processors and other devices, and newer entrants such as conduction-cooled switching products, the use of cPCI is rising rapidly.
