Description
Nova’s NGFCPFCRK-Series frequency converters are high-reliability three-phase power sources specifically designed for demanding applications in high shock, vibration, humidity, and EMI environments. They can be built to meet MIL-STD-1399, MIL-STD-810, MIL-STD-167, MIL-S-901, MIL-STD-461, and other standards optionally. The NGFCPFCRK Series utilizes an advanced high frequency topology for light weight, compact form factor from 1-5U. These models are especially suitable for severe environment and high reliability applications such as:
- Military Applications: HMMWV, UAV, Shipboard, Submarine, Aircraft and Mobile Power Units, Shelters
- Aircraft Power
- Communications Systems
- Cellular Sites
- European Power / Export Testing
- Power Conditioning & Frequency Stabilization
- U.S. Power Abroad
- Railroad Signaling Power
