Electronic Components and Supplies (IEC) has made some related power | the voltage stabilizer standards, such as dc stable power supply standard: IEC478.1-1974 “dc stable output power source term”; IEC478.2-1986 “dc stable output power rating and performance”; IEC478.3-1989 “dc stable output power transmission of electromagnetic interference benchmark level and measuring”; IEC478.4-1976 “dc stable output power in addition to the radio frequency interference of the test method”; IEC478.5-1993 “dc stable output power electric resistance near field magnetic field component measurement”. This set of standards promulgated earlier time, our country has not corresponding national standards promulgated. And the dc power supply of electronic industry standard stable SJ2811.1-87 “general dc power supply terms and definition, stable performance and ratings”, SJ2811.2-87 “general dc power supply stable test method” has been issued by the 13 years. Long-term since, the two standard dc power supply to our country stable scientific research production play a very significant role.
Electronic Components and Supplies (IEC) in 1980 has issued a IEC686-80 “exchange stable output power”, with reference to the standards of China’s national standard GB/T “ac stable output power general specification” has been completed and approval, the standard of the terminology, technical requirements and testing methods according to the IEC686, in addition, and add environment test requirements and test method, the quality assessment procedures, mark, packing, transportation, storage and requirements, making it a can guide the ac power the whole process of developed a complete technical specifications.
In 1994, the ministry of electronic industry promulgated the electronic industry standard SJ/T10541-94 “anti-interference type interfluent stable power supply general technical conditions” and SJ/T10542-94 “anti-interference type interfluent stable power supply test method”, the standard by the China power supply society stable power supply professional committee of communication and domestic related power supply manufacturer, and testing institutions responsible for compiling, the regular and anti-jamming type interfluent stable power supply, the technical requirements of the environmental requirements and corresponding test method, quality inspection rules do detailed regulations. Since the implementation of the standard released, in ac regulator, technology has been used widely in the field.
Some other standards, such as and IEC443-1974 “stable power supply device used for measuring of the ministry of electronic industry in our country corresponding standard SJ/Z9035-87″ stable power supply device used for measuring “also be in a certain range has been applied.
In recent years the rise of switch power supply and uninterrupted power supply, China also formulated relevant national standards, such as GB/T14714-93 “small small-sized computer system with equipment switching power supply general technical conditions”, GB/T14715-93 “information technology equipment with uninterrupted power supply general technical conditions” and so on, in the relevant fields is also widely used.
The original four machine department standards SJ1670-80 “electronic equipment power terms, it’s been 20 years, many terms in explanation of the already and the current standard produced contradiction, therefore, this year the ministry of information industry on the standard standardization organization revised, some remained in the original standard is still applicable for terms, the standard of classification method made major adjustment, the revision of the standard mission is to enhance the applicability of the standard, therefore, will be based on the most commonly used in the field of modern power some classes of power for classification, given their respective terms and definitions, the general part of a single chapter, each chapter of terms and definition of the international standard and with reference to relevant national standards, the report by the standard finish.
