Nova Electric’s Ultra Lightweight Series rugged, military UPS System can be modified for the most severe environment applications, including aircraft. These are the UPSs of choice for Boeing, EADS, the US Coast Guard’s C130 CASPER, and many other high profile airborne applications worldwide. Typically, these rugged UPS models have aircraft power input of 115/200 VAC, 400Hz, three-phase wye and pure sinewave output of 120 VAC, 60 Hz, single-phase. These rugged, military UPS Systems contain all of the features standard on other Ultra Lightweight Series units, as well as additional features that make them ideal for aircraft applications. These features include:

RTCA/DO-160G Qualified: Select units were tested successfully by Boeing and Rockwell Collins to meet RTCA/DO-160G for:

  • Rapid Decompression: Section 4 Cabin Pressure (8K) to Max Operating Alt (35K) in 15 sec; Hold for 10 min
  • Crash Safety Sustained: Section 7, Cat B – Up = 3.0g – Down = 6.0g – Fwd = 9.0g – Aft = 1.5g – Side =4.0g
  • Explosive Atmosphere: Non-Ignition Test Sec. 9.6.2, Cat E
  • Humidity: Section 6, paragraph 6.3.1 (Category A)
  • Random Vibration Testing: Section 8 (Category R, Fixed-Wing), paragraph 8.7.2, Figure 8-1: Aircraft Type 2, Test Category S, Zone 2, Curve B
  • Operational Shock Testing: Section 7 (Category B), paragraph 7.2, Standard operational, Peak value 6 g, Nominal duration 11 ms.

Additional Ruggedization to meet MIL-STD-810: 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. For additional protection against humidity, optional low-draw heating elements can be included within the unit, and optional drain holes can be placed strategically inthe base of the chassis to allow any formed condensation to escape.

Internal EMI Reduction Package to meet MIL-STD-461: The design of these units is specifically focused on reducing EMI emissions. The UPS contains substantial internal filtering to minimize EMI emissions. Inputs which may be susceptible to transients are protected by several methods. The compact rack mount 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.

MIL-STD-461E: CE101, CE102, CS101, CS114, CS116, RE102, RS101, and RS103 Note: Qualification testing was performed with optional premium batteries required to meet temperature testing requirements.
