WHEN EVERY POUND COUNTS! Nova’s Ultra Lightweight Galaxy-Series rugged, true online DC UPS systems are high-reliability power sources specifically designed for demanding applications in high shock, vibration, humidity, and EMI environments in compliance to MIL-STD-1399, MIL-STD-461, MIL-S-901, MIL-STD-167, MIL-STD-810, MIL-STD-740, DOD-STD-1399, and RTCA/DO-160. They supplement our comprehensive lineup of Ultra Lightweight Galaxy-Series rugged, true online AC UPS systems.

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

  • 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

These UPSs are among the lightest in the industry, thanks to their use of advanced Lithium Iron Phosphate batteries, which are contained in a retractable drawers for ease of service. Separate rack mount battery modules can be added to extend run time as required, from several minutes to several hours or more. Sealed, maintenance-free VRLA batteries are also available as standard, along with premium premium Cyclon cells for extremely wide temperature range and long life.

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. Standards met include MIL-STD-1399, MIL-S-901, and MIL-STD-167 for shipboard, DO-160 for avionics, MIL-STD-461 for EMI, MIL-STD-740 Structureborne noise measurements, MIL-STD-810 for shock, vibration, and humidity, and other related standards.

The Ultra Lightweight UPS has a highly flexible design architecture which allows adaptation to practically all military applications. Its Power Factor Correction circuit allows compliance to the CE mark’s “Low Voltage Directive,” so it can operate on a wide input range from 100-250 Volts AC, on any standard frequency including 50, 60, or 400 Hz.

Many communication platforms are supported, including RS232, SNMP, RS485, and CANbus. A multitude of connectors are available, as are different types of chassis slides, and a host of other options to tailor the unit to unique applications as required.

Nova Electric’s Ultra Lightweight UPS are deployed in countless high profile military programs aboard Naval ships and submarines, on satellite trailers and mobile shelters, and 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 Technologies, General Dynamics, DRS, BAE, L3Harris, all branches of the US Armed Forces, and US allied forces worldwide.
