provided that, in previous full compliance tests, it has been shown to have current emissions( a6 i p: }/ ]* T' t0 j d4 F; F
below 60 % of the applicable limits and the THD of the supply current is less than 15 %. The

我之前完成测试时满足谐波低于60%，THD低于15%。
u2 G$ i, Q3 m6 z那么我升级之后的产品如果功率在原来的±20%之间，THD测试值仍低于15%。我就认为是符合要求的？
