A few days ago, RECOM issued brand-new 20W 50W DC/DC converter series PowerlinePlus, there are six sections of new module now: RPP20-S_D, RPP20-S_DW, RPP30-S_D, RPP30-S_DW, RPP40-S, RPP50-S, adopt RECOM new ICE Technology, it is the lowest that can make the internal heat decrease, and reach most heat-conductions the circumference.

The brand-new converter can offer high-order efficiency at the price lower than the traditional professional converter by a wide margin. According to representing,PowerlinePlus with - the case temperatures of 45 ℃ to +120 ℃working range,built-in and be fully output protective when receivinged of Class B EMC electric-wave filter, satisfiable multiple military affairs, aeroelectronics and applied in industry unique requirement of high-order. PowerlinePlus combines designing and revolutionary integrated air-cooling fin chassis of a high efficiency, offer the higher power within the range of more broad temperature, require less spaces and cost with the grade solution to what these tight severe application that require offered than before at the same time.

RPP20-S_D possesses and inputs the voltage range, bes single or exports selecting, 2kVDC to isolate in one pair of groups at 2:1, the built-in EMC electric-wave filter offers 20 watts of power, and operate with the efficiency up to 90%, by offering the environment from - 45 ℃ to +100 ℃ to operate the temperature range and have no derating, and only adopt the external packing of 2 x 1.2. RPP20-S_DW is similar to RPP20-S_D, but offer ultra broad inputting the voltage range at 4:1.

RPP30-S_D possesses and inputs the voltage range, bes single or exports and selects in one pair of groups at 2:1, 3kVDC isolates, the built-in EMC electric-wave filter offers 30 watts of power, and operate with 92% of the efficiency, offer and operate the temperature range and have no derating from - 45 ℃ to +96 ℃ environment, external packing only 2 x 1.2. RPP30-S_DW is similar to RPP30, offers ultraly and broadly and inputs the voltage range at 4:1.

RPP40-S possesses and inputs voltage range, single output, 3kVDC to isolate at 2:1, the built-in EMC electric-wave filter offers 40 watts of power, and operate with 92% of the efficiency, by offer and operate the temperature range and have no derating from - 45 ℃ to +89 ℃ environmenting, adopt 2 x1.2 external packing.

GE Fanuc intellectual platform claim, incorporate his bulky aviation electron, employ the intersection of determinacy and the intersection of Ethernet and technology in the solution a few days ago. This kind of new technology is called time and touched off Ethernet (TTEthernet) ,Developed by TTTech Computertechnik AG Company of Vienna of Austria, meet to reliable fault-tolerant safe key the intersection of solution and demand that increase day by day bandwidth high and augmentability high. Based on TTEthernet product are authorized through DO-178 and DO-254, is use for connecting the system on the safe key platform. These products can guarantee to receive and dispatch the information package according to the regular hour, this kind of determinacy contributes to preventing the complex system from presenting the aberration or involuntary interrupt.

"Ethernet is nowadays most general communication computing technique, have the characteristic of high bandwidth, simplifying and low-cost. " The aviation electronic product manager Ben Daniel of GE Fanuc intellectual platform says. "However, it is not actually there was a determinacy, but this was exactly a characteristic needed in safe key application such as a civil aircraft. TTEthernet has met this demand and offered the exciting one because of the open canonial scheme, thus offer for technology such as traditional MIL-STD-1553 and ARINC-429 and substitute the solution. "

TTEthernet is that group has built up and offered the sufficient expansibility when Ethernet is real, among them the key advantage which faces the real-time system includes inherent high throughput, low complexity, remarkable expansibility and lower systematic life cycle cost. Other numerous the intersection of aviation and electronic the intersection of bus line and technology but speech, in construct, maintain and train the cost on lower by a wide margin TTEthernet.

TTEthernet utilizes the strong service to expand the epitaxy of traditional Ethernet, has met the determinacy or increasingly high requirement of correlation system of security prerequisite to time. The open technology of uniting the network of TTEthernet faces real-time industrial automation, Aero-Space and other transportation sector application, having realized it with AFDX and interoperability of ARINC 664, thus incorporate the ability of its determinacy in the Off-The-Shelf network solution.

At present, airborne equipment and system that ARJ21 uses also mainly rely on import, because China's domestic aviation electronic system is still only limited to military application. " Relieve and grow for the 12th and say, because the life-span of the military plane is only 1/10 of the civil aircraft, so standard and military plane of the people machine's on-board electronic device are not quite alike, and the people machine's airborne equipments all need through the seaworthiness standard, in order to guarantee the great safety.

The relevant expert introduces, in recent years, the electronics industry of China has already made very great progress, but seen from the overall situation of electron trade, China has performed the role of a equipment processing factory, the profit is very thin. Meanwhile, most apparatus outmoded Chinese enterprise, craft lag behind, new product the intersection of development ability and insufficient scheduling problem restrict the intersection of Chinese and the intersection of electronic devices and components and survival and development of industry still.

So, the key components and parts basically rely on import. The electron trade of China is in low-level, expensive, small-scale, state managed scatteredly all the time. With low technical content doing related enterprise to be many, it engaged in Hi-Tech enterprises of plant to be little; There are many enterprises depending on foreign basic material and apparatus carry on simple reproduction, the enterprises with foreign exchange earning of the independent intellectual property right are few.

At present, a boat in China has some companies producing airborne equipment under command, but mainly form a complete set with the military plane. The relevant civil aviation's expert points out, if develop the the people machine project, market demand may drive these companies to develop electronic device of the people machine, and the big plane is in order that the aviation electron is industrial " The civilian production by the defense industry " Have offered the opportunity.

In addition, the big plane also needs a large number of instrument instrumentations. And at present, the domestic instrument because the product reliability is discrepancy, the mean operating time between failures is 1- 2 pieces of order of magnitude lower than foreign products, China needs importing 52.87% of the total demand of product market of the instrument, middle-grade products and a lot of key spare part foreign enterprises have accounted for more than 60% of the market share, and the large-scale, high-accuracy instruments nearly all rely on import.

At present, enterprises can produce some aviation instruments in China's aviation system, a large number of instruments are to depend on enterprise's production outside the aviation system.
