Switching Power
Market analysis of the domestic industrial switching power supply - power switch - electrical industry
Switching power supply with its energy efficient, small size and light weight advantages gained in the industry wide application, has become an important basis for industrial products. Current switching power supply industries of the Mainland market, most major companies in 90 years in the 20th century into the mainland market, the establishment of industrial switching power production plants is gradually increasing the number of foreign brands, the market competition.
Switching power supply Its high efficiency, small size and light weight advantages gained in the industry wide application, has become an important foundation for industrial products. Current switching power supply industries of the Mainland market, most major companies in 90 years in the 20th century into the mainland market, the establishment of industrial switching power production plants is gradually increasing the number of foreign brands, the market competition.
Currently the industry's definition of the scope of industrial switching power supply is not consistent, therefore, industries and enterprises in industrial switching power supply market knowledge are not the same. Recently, in Beijing JFUnited Consulting Co., Ltd. (JFUnited) launched the "2009 China Industrial Power Supply Market Research Report", the report of the "industrial switching power supply" means the output power of less than 1,500 W (including 1,500 W), including single and multiple output voltage, used machinery, electricity, rail transport, Metallurgy , Petrochemical, automobile, cement, coal and other industrial areas (not including communications, medical, LED, business computers, buildings and so on) of the switching power supply products (not including power supply module). Based on the above definition, JFUnited (JFUnited) status from the switching power supply market, the industry's demand for both application areas of industrial switching power supply market in mainland China to do the corresponding analysis.
2008 began to slow growth of industrial switching power supply market in 2009, less than 7% growth rate is expected, the market prospects for a short time is more confused, but the staying power than the foot.
2008 Industrial Switching Power Supply market size of about 1.18 billion yuan. In the second half of 2008 before the main competition of industrial switching power supply manufacturers, most enterprises Sell Rapid growth of industrial switching power supply market to be optimistic. However, the third quarter of 2008, subject to Financial Crisis and other environmental influences, most business slowdown, a negative growth of some enterprises, the mainland market growth of industrial switching power supply fluctuations. 2007-2008 growth of industrial switching power supply market, 12.7%, higher than the 2007 growth rate drop back. Affected by this, industrial switching power supply market leading supplier of environmental changes that the financial market development on the switching power supply greater impact on the market outlook is expected to also tend to be conservative, the overall market growth in 2009 is expected to greatly decreased, less than 7% ; and industrial switching power supply after 2010 development trend is difficult to predict.
Although the financial crisis caused by the industrial switching power supply market, a relatively large impact, but companies upgrading of downstream applications, driven by demand in emerging industries, and support national policies and other factors on the development of the mainland power market has played a positive role. Therefore, as the financial crisis eased, the mainland industrial switching power supply market will show rapid development trend.
Industrial switching power supply and high market concentration, Ming Wei, Siemens became the focus of market competition
Industrial switching power supply high market concentration, industry, the top 10 enterprises up 76.1% market share. Among them, the highest market share of two enterprises are specified latitude and Siemens. Ming Wei, Siemens, respectively, as the current industrial switching power supply market in mainland China plate switching power supply, rail switching power supply in the field of representative enterprises, enterprise competition for industrial switching power core. And Other In addition to the main business companies compete with those two things, also because the company portfolio, product applications and so on specific occasions in the formation of intense competition, such as power field (De Chong, Yufeng, the three basic, etc.) PLC Supporting areas (Siemens, Hui Peng, Chen Ou, Moore, etc.), industrial switching power supplies customized business (in Chaoyang District, Sun, etc.), Japanese-funded enterprises (Kosovo, TDK Miranda) and other features have their own competition.
JFUnited (JFUnited) of industrial switching power supply market, according to the company's market share and product level competition is divided into five camps:
First camp: Only Ming-wai, a product targeted at the low end, switching power supply China's market share more than 21.4%; Ming Wei lower 2007-2008 growth, market share has been reduced.

why do the refridgerator grows mould after switching the power off for a long prriod of time?
why do the refridgerator grows mouldy after switching the power off for a long prriod of time? is it safe to use it again if i switch it back on?
When you switch off the fridge, the cold air inside condenses in proportion to the outside air temperature and produces moisture, which you may see in the form of droplets inside. The bacterias inside would've been dormant as the temperature would've been between 3C to 6C (38F to 43F) when the fridge was switched ON. But, when its OFF, the bacterias become active in warmer temperatures, favoured by the moisture developed by condensation and forms the mould.
You must definitely clean the fridge and preferably sanitize (availabe in all super stores) before switching back on. It is a healthy & safe action.
