The capacitance of the capacitor is to be within ±5 percent of the capacitance rated for the ballast. 1 o4 E3 O7 p# Y( o0 n.

标准前后没有看.单看这两段,54.2.2 要求试验时实际灯功率应在额定灯功率±5%的偏差范围内;54.2.3是说要保证试验时实际灯功率应在额定灯功率±5%的偏差范围内,可以通过调节电压的方式获得,但电压调节范围也在额定电压的±5%之内(否则应换电器或灯).作者: wangping0930 时间: 2007-11-7 10:35

因为镇流器是高频的,所以一般的功率仪是测不到的,用示波器测过电压,但是电流没有测到,万用表也测不出.作者: caballo3157 时间: 2007-11-7 10:45
楼主这里关心的好象主要是镇流器的输出功率，即灯功率。5 _8 _3 v# V' S( [# F
如果要测峰值电压，许多许多多功能数字表也是可以的。作者: hiker 时间: 2010-7-9 11:23
HID整流器应该使用UL1029标准啊！怎么涉及到ＵＬ１５３标准？不懂，请指教
