Description

The transformer-isolated Galaxy Series Rugged Inverters are designed for harsh environment, military, and rail applications, and feature an optional advanced Internal Suppression Filter Network (ISFN) to suppress the significant transients usually associated with these types of conditions. They can be built to meet MIL-STD-810, MIL-S-901, MIL-STD-1472, MIL-STD-461, MIL-STD-167 and other standards optionally. Transformer-isolated topology makes these Inverters suitable for very high inrush loads, such as motors and compressors. These models utilize the most durable components, offering maximum field-proven reliability for severe environment and high reliability applications such as:

  • Rail and Trolley Applications
  • Military Applications: Including HMMWV, UAV, Shipboard, Submarine, Aircraft, Mobile Power Units, Shelters, Transportable Systems, Tactical Systems, Ground Support, and more
  •  Heavy-Duty Industrial Applications
  • Demanding Commercial Applications
  • Communications Systems
  • Utility Applications
  • MIL-STD-810
  • MIL-S-901
  • MIL-STD-167
