22、controlled voltage filament lamps at frequencies deviating from the supply frequency. Attention is drawn to the fact that operating frequencies below 20 kHz may cause audio noise. NOTE CISPR requirements regarding radio interference have to be observed in some countries. In order to obtain satisfact
23、ory performance of filament lamps and electronic convertors, it is necessary that certain features of their designs be properly coordinated. Page4 EN61047:2004 4DC OR AC SUPPLIED ELECTRONIC STEP-DOWN CONVERTORS FOR FILAMENT LAMPS PERFORMANCE REQUIREMENTS 1 Scope This International Standard specifies
24、 performance requirements for electronic step-down convertors for use on d.c. supplies up to 250 V and a.c. supplies up to 1 000 V at 50 Hz or 60 Hz with operating frequencies deviating from the supply frequency, associated with tungsten halogen lamps as specified in IEC 60357 and other filament lam
25、ps. NOTE 1 The tests in this standard are type tests. Requirements for testing individual convertors during production are not included. NOTE 2 Requirements for convertors which incorporate means for varying the lamp power are under consideration. NOTE 3 It may be expected that convertors complying
26、with this standard will ensure satisfactory operation between 92 % and 106 % of rated supply voltage of filament lamps with rated lives greater than 200 h and rated voltage less than 50 V. NOTE 4 There exist regional standards regarding the regulation of mains current harmonics for end-products such
27、 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. 2 Normative references The following referenced documents are indispensable for the application of this documen

NOTE The requirements and tolerances permitted by this standard are based on testing of a type test sample submitted by the manufacturer for that purpose. In principle this type test samp
34、le should consist of units having characteristics typical of the manufacturers production and be as close to the production centre point values as possible. It may be expected with the tolerances given in the standard that products manufactured in accordance with the type test sample will comply wit
35、h the standard for the majority of the production. Due to the production spread however, it is inevitable that there will sometimes be products outside the specified tolerances. For guidance of sampling plans and procedures for inspection by attributes, see IEC 60410. 4.2 For tests which are carried
36、 out with a lamp or lamps, this lamp(s) shall fulfill the following requirements.
