标题: IEC60335-1功率测试问题 [打印本页] 作者: Misslanlan 时间: 2022-12-1 14:30 标题: IEC60335-1功率测试问题 小白发问：标准原文是下面这样，那对于标有电压上下限，比如220~240V，1000W的电动器具，到底是上下限电压都要测试功率，还是只测试230V的功率，怎么判断输入功率是否和电压算数平均值有关呢。 Test carried out at upper and lower limits of theranges for appliances with one or more ratedvoltage ranges, unless the rated power input is related to the arithmeticmean value6 ]$ h: ]* C' l1 j- p, {.

看产品标称，只标1000W这个功率按算术平均值进行测试，否则分别测试2个电压，分别标出功率。作者: hillerhuang 时间: 2022-12-2 17:56
电压上下限差值不超过电压10%的,按照电压上下限的平均值测试.电压上下限差值超过电压10%的,按照下限和上限都测试.作者: jtt1471025811 时间: 2022-12-5 11:52

比如适配器标100-240V, 上下限值超了10%, 就不能按电压的算数平均值算。作者: XIAXI 时间: 2023-2-20 14:49
