RTCA/DO160 is available optionally. These models offer 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, Drone Systems, and more
  • Heavy-Duty Industrial Applications
  • Demanding Commercial Applications
  • Communications Systems

These Converters have a highly flexible design architecture which allows adaptation to practically all military applications. The Power Factor Correction circuit allows compliance to the CE mark’s “Low Voltage Directive,” so the units 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. 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 different types of chassis slides.

Nova Electric’s Ultra Lightweight Converters 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 unit is specifically focused on reducing EMI emissions. The unit 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.
