Expand diagram for more details on the configurable nature of NAI's Rugged Power Supplies.

North Atlantic Industries (NAI) has over 40 years’ experience providing a wide variety of modified COTS and custom power supplies—including configurations that meet VME, cPCI and VPX (VITA 62) requirements — for rugged defense and industrial applications.

Our Configurable Open Systems Architecture™ (COSA®) leverages a discrete component design approach. This allows our customers to select from a full-feature library (see diagram at right) to create high reliability power solutions that meet their specific requirements - with little or no NRE.

Our use of proven discrete component technology allows:

  • Wider input ranges
  • Higher reliability
  • Lower risk designs
  • More efficient layout of components compared to alternative, pre-packaged product designs.

This approach also provides more control and greater ability to address your special power and signaling needs. 

Designs are pre-qualified to MIL-STD-810 & VITA 47 environmental compliance requirements as well as integrated EMI filtering per MIL-STD-461 and input transient protection per MIL-STD-704, MIL-STD-1399 & MIL-STD-1275.

Below are some examples of modified power products previously designed to meet challenging customer requirements. Please contact us today at +1 631.567.1100 or Request A Quote to discuss your specific needs with an NAI representative.
