WHEN EVERY POUND COUNTS! Nova’s Ultra Lightweight Galaxy-Series rugged, True Online UPS systems are high-reliability power sources specifically designed for demanding Naval applications in high shock, vibration, humidity, and EMI environments in compliance to MIL-STD-1399 and MIL-STD-461.

These UPS models utilize True Online technology, offering maximum field-proven reliability for severe environment and high reliability applications such as:

  • Military Applications: Including Shipboard, Submarine, HMMWV, UAV, Aircraft, Mobile Power Units, Shelters, Transportable Systems, Tactical Systems, Ground Support, and more
  • Heavy-Duty Industrial Applications
  • Demanding Commercial Applications
  • Communications Systems

Standard input is 115 VAC, 60 Hz, three-phase Delta shipboard power, and output is 120 VAC, 60 Hz, single-phase, with up to 3 KVA / 3 KW continuous output power. Separate 3U rack mount battery packs featuring premium Cyclon battery cells provide run time as required, from several minutes to several hours or more. These Cyclon cells are sealed, maintenance-free, and feature -40° to +80°C operating range and a useful life of 8-12 years @ +25°C ambient.

As you’d expect from Nova Electric, variations of this proven design have repeatedly passed formal qualification testing on a variety of military platforms including shipboard, vehicular, and airborne. Models shown on this page have been formally tested to MIL-STD-1399 Section 300B and MIL-STD-461G. Compliance to other MIL-STDs such as MIL-S-901, MIL-STD-810, and MIL-STD-167 is available optionally, either through formal testing at accredited third party laboratories or via similarity to other previously qualified models.

Many communication platforms are supported, including RS232, SNMP, RS485, and CANbus. A multitude of options are available to tailor these units to nearly any application.

Nova Electric’s Ultra Lightweight UPS are deployed in countless high profile military programs aboard Naval ships and submarines, and on satellite trailers, mobile shelters, military ground vehicles and aircraft, with a field-proven MTBF exceeding 100,000 hours. These units are the first choice for the world’s leading defense contractors including Lockheed Martin, Boeing, Raytheon, General Dynamics, DRS, BAE, all branches of the US Armed Forces, and US allied forces worldwide.

Internal EMI Reduction Package to meet MIL-STD-461: The Ultra Lightweight UPS Systems shown herein are designed to comply with the requirements of MIL-STD-461G using shielded input, output, and data cables. Test data to other revisions of MIL-STD-461 is available for select models. (If the input and output cables are not shielded, additional filtering may be required for full compliance to MIL-STD-461.)

Please note: Not all models and choices of input voltages and output voltages shown in the model chart have been formally tested for each of the following MIL-STD-461G parameters shown below. In such cases, Nova cannot guarantee full compliance without a formal testing program for your specific UPS configuration, available optionally. Please consult the factory for details.

Additional Ruggedization: The UPS System’s construction is extremely robust, and ruggedized throughout. All components and modules within the unit are mounted using additional steel brackets and heavy-duty stainless-steel hardware, which is then further secured using Loctite and RTV where required. All boards are conformal-coated (Acrylic MIL-I-46058 Type R) for maximum resistance to potential condensation and fungus growth. Formal testing to MIL-S-901, MIL-STD-810, MIL-STD-167, and other environmental standards is optional.
