Nova frequency converters are high-reliability power sources specifically designed for demanding applications in high shock, vibration, humidity, and EMI environments. They can be built to meet MIL-STD-810, MIL-S-901, MIL-STD-1472, MIL-STD-461, and other standards optionally. Transformer-isolated topology makes these Converters suitable for very high inrush loads, such as motors and compressors. They are suitable for severe environment and high reliability applications such as:

  • Military Applications: HMMWV, UAV, Shipboard, Submarine, Aircraft and Mobile Power Units, Shelters
  • Aircraft Power
  • AC Power from vehicle battery
  • Communications Systems
  • Cellular Sites
  • European Power / Export Testing
  • Power Conditioning & Frequency Stabilization
  • U.S. Power Abroad
  • Railroad Signaling Power – 25, 91.667, 100, 200, 209, and 250 Hz. available
