WHEN EVERY POUND COUNTS! Nova’s Ultra Lightweight Galaxy-Series rugged, true online 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.

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 its use of advanced Lithium Iron Phosphate batteries. Separate battery modules can be added to extend run time as required, from several minutes to several hours or more. Standard sealed 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. Three phase input is also available if desired. Its isolated output permits grounding the input neutral and / or optionally grounding output neutral as well.

Many communication platforms are supported, including RS232, SNMP, RS485, and CANbus. A multitude of connectors are available, as are solid state or electromechanical bypass, 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, 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 design of this military UPS unit is specifically focused on reducing EMI emissions. The military UPS contains substantial internal filtering to minimize EMI emissions. Inputs which may be susceptible to transients are protected by several methods. The compact chassis is specifically treated with low surface resistivity finishes on the interior. All aluminum parts are treated with clear irridite. The steel parts are treated with zinc plate, followed by a clear chromate. Paint method via ANSI-61 gray is designed to assure excellent bonding of mating sheet metal parts. All input and output ventilation filters include metal honeycomb-style or mesh filters. This military UPS unit was tested and qualified as follows:

MIL-STD-461E: CE101, CE102, CS101, CS114, CS116, RE102, RS101, and RS103.
