Clauses 12 through 15 each detail specific requirements for a particular type of ballast. This standard covers inductive type ballasts for use on a.c. supplies up to 1 000 V at 50 Hz to 60 Hz associated with discharge lamps, having rated wattage, dimensions and characteristics as specified in the relevant IEC lamp standards.NOTE 1 For certain types of discharge lamps an ignitor is required.NOTE 2 Extension of the standard to cover ballasts incorporating, or for use with, series capacitors is under consideration.NOTE 3 The performance requirements of ballasts for tubular fluorescent lamps are covered by IEC 60921.NOTE 4 There are regional standards regarding the regulation of mains current harmonics for end-products such as luminaires and independent control gear. In a luminaire the control gear is dominant in this respect. Control gear, together with other components, should comply with these standards.【中国标准分类号】: K74【国际标准分类号】: 29_140_99【页数】: 62P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
