Powertek's Lightweight Frequency Converter and cabinet AC Power Sources

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-STD-167, MIL-STD-1399, MIL-STD-1472, MIL-STD-461, and other standards optionally. GL-Series models utilize high frequency PWM topology, offering significant volume and weight advantages suitable for severe environment and high reliability applications such as:

✓ Military Applications: HMMWV, UAV, Shipboard,
Submarine, Aircraft and Mobile Power Units, Shelters
✓ Aircraft Power
✓ Aircraft Ground Power
✓ Avionics power
