IEC60335-1的疑问——第19章

有一款电热器具，普通发热丝的，标识220-240V,1000W
请问19.2的条款上0.85倍的输入电压，是指220V对应的电压，还是1000W的0.85倍电压？

(220/230)^2 x 0,85 x 1000

指220V对应的功率的0。85倍

输入功率稳定后提供0.85倍额定输入功率所要求的电压

(220/230)^2 x 0,85 x 1000

1000W是对应230V电压的，所以，加分。

试验过程中施加实测输出850W时所对应的电压，一直不变

220V对应的功率的0.85倍。
见
5.8.3 For heating appliances, and combined appliances, marked with a rated power
input range, when it is specified that the power input is equal to the rated power input
multiplied by a factor, the appliance is operated at
– the upper limit of the rated power input range multiplied by this factor, if greater than 1;
– the lower limit of the rated power input range multiplied by this factor, if smaller than 1.

你所说的是标输入功率范围的产品，而LZ的产品是标的是平均电压下的功率
