觉得不正常

如果产品能於50-60Hz下使用，这样标没问题啊。

upobeyond 发表于 2016-2-23 20:10

50-60Hz没有问题，充电器支持就可以

kuzhuan2008 发表于 2016-3-14 18:42

可以的,代表范围哈

60335-1
7.3 Appliances having a range of rated values and which can be operated without
adjustment throughout the range shall be marked with the lower and upper limits of the range
separated by a hyphen.
NOTE 1 Example: 115-230 V: The appliance is suitable for any value within the marked range (a curling iron with a PTC heating element or an appliance incorporating an input switch mode power supply).

---即用户不可调节的，50-60

Appliances having different rated values and which have to be adjusted for use at a particular
value by the user or installer shall be marked with the different values separated by an
oblique stroke.
NOTE 2 Example: 115/230 V: The appliance is only suitable for the marked values (a shaver with a selector switch).

--用户可调节的，50/60

看起来像是写错了, 但这种标法本身是没有问题的

正解，深表赞同

你认证的报告和铭牌是标50/60Hz么？

cmk1991 发表于 2018-4-12 22:30

那标示50/60Hz和50-60Hz测试输入有什么不同呢

正解就是如楼主所说的！实际由于4706.1中说的有点模糊，标的状态有两种，问题都不大！但电压4706.1中就有这明确的要求了
