如议题, IEC61000-3-2, 7.3.a 对于调光驱动电源测试要求的理解.标准要求如下:
7.3 Limits for Class C equipmenta) Active input power >25 WFor lighting equipment having an active input power greater than 25 W, the harmoniccurrents shall not exceed the relative limits given in Table 2.
However, the limits given in Table 1 apply to incandescent lighting equipment that hasbuilt-in dimmers or consists of dimmers built in an enclosure.
For discharge lighting equipment that has built-in dimmers or consists of independentdimmers or dimmers built in an enclosure, the following conditions apply:
– the harmonic current values for the maximum load condition derived from thepercentage limits given in Table 2 shall not be exceeded;
– in any dimming position, the harmonic current shall not exceed the value of currentallowed in the maximum load condition;
– the equipment shall be tested according to the conditions given in C.5.
对于调光驱动电源怎样测试才是合格的?按此要求吗?
However, the limits given in Table 1 apply to incandescent lighting equipment that hasbuilt-in dimmers or consists of dimmers built in an enclosure.
在标准中C5.3中又有这样的要求?
If a luminaire has a built-in dimming device, the harmonic currents shall be measured at themaximum load of the lamps as specified by the manufacturer. The setting of the dimmingdevice is varied in five equidistant steps between the minimum and the maximum power inorder to obtain comprehensive results.
真的,让人难以理解, 请各位亲们帮帮手哦
