Power source standard

International Electrotechnical Committee (IEC) the standard that had established a few concerned power source, if spread standard of stabilized power supply continuously: IEC478.1 - 1974 " dc outputs term of stabilized power supply " ; IEC478.2 - 1986 " rating of dc output stabilized power supply and function " ; IEC478.3 - 1989 " the fiducial n that dc outputs stabilized power supply to conduct electromagnetism to disturb and measure " ; IEC478.4 - 1976 " dc output stabilized power supply disturbs the experiment method outside except radio frequency " ; IEC478.5 - 1993 " of heft of magnetic field of near field of sex of reactance of dc output stabilized power supply measure " . This one standard promulgates executive time earlier, our country's corresponding state level had be notted promulgate. And the SJ2811.1 of electronic occupation standard of concerned dc stabilized power supply - 87 " term of stabilized power supply of general direct current and definition, function and rating " , SJ2811.2 - 87 " stabilized power supply of general direct current checks a method " already released carry out 13 years. Long-term since, the scientific research that these two standards shed stabilized power supply continuously to our country went to very big effect since production.

International Electrotechnical Committee (IEC) promulgated IEC686 1980 - 80 " communication outputs stabilized power supply " , consult the GB/T of level of our country state that this metric system decides " communication output stabilized power supply is general and normative " had signed up for batch finish, requirement of the term in this standard, technology and experiment method consulted IEC686, besides, increased an environment again program of assess of experiment requirement and experiment method, quality, mark, pack, carry, the requirement such as keep in storage, a when make its become a can directive alternating current source to develop whole process complete technology is normative.

1994, former Ministry of Electronic Industry promulgated SJ/T10541 of electronic occupation standard - 94 " regulated power supply of interference rejection communication is current technical condition " with SJ/T10542 - 94 " regulated power supply of interference rejection communication checks a method " , this standard is learned to communicate major of stabilized power supply by Chinese power source the power source manufacturer related committee and home, place and detect the responsible work out such as the orgnaization, right common model regulation of the technical requirement with regulated power supply of interference rejection communication, environment requirement and corresponding experiment method, quality inspection made detailed provision. This standard releases solid inflict to come, in communication domain of stabilized voltage technology received wide application.
