标准中关于正常工作的有定义用什么食物测试,当然也可以在说明书中自定义。作者: 小小黑 时间: 2012-9-14 14:07
如果不去考虑大功低标的问题的话,只要额定电压是在220-240V 50/60Hz的条件下,那么250V 2.5A插头和0.5mm2的电源线可以使用;如果要考虑到实际功率300-600W的话,在220-240V 50/60Hz 额定电压下250V 2.5A插头不能使用(只能使用250V 16A的插头);0.5mm2电源线只要不超过2米即可使用; / Z @+ E3 P e( z2 | n需要值得注意的是:一般大功小标是不被客户接受的,小功大标倒是很多客户都喜欢。作者: aaainmaya 时间: 2012-9-14 14:59 本帖最后由 aaainmaya 于 2012-9-14 15:01 编辑 9 p" a2 m7 |+ m+ S4 v , u5 W8 S$ o9 F! {6 m- l3.1.6 ) L# a.
