Maximizing power while minimizing size and weight
Vicor provides high-density power solutions critical for reducing size and weight while supporting the needs of increasing capabilities of defense systems. Rugged, efficient power modules – and open standard VITA and SOSA aligned power supplies – support the entire power delivery network from AC or high voltage to a MIL-STD 270V or 28V bus, and then to downstream loads. Patented technologies provide low EMI and stable power delivery, while the flexibility and scalability of the modular approach make change quick and easy. The high power and current delivery, strong thermal performance, and reliability of Vicor products ensure longer mission times and superior system endurance, as they have for more than 30 years in aerospace and defense applications.
