I don't have to worry about the difference between 50Hz and 60Hz for the AC adapter attached to the iPhone?
A very cool question has jumped in.Is it the difference between the plus of the AC power supply and the minus replacement to one second, the difference between the "power frequency"! The conclusion is that you don't have to worry about it, but why is this question and what is the current situation?Let's explain it.
In Japan, due to the difference in generators purchased by the lighting company in the Meiji era, the commercial power supply frequency is divided into two parts by Fuji River in Shizuoka Prefecture and the Itoigawa River in Niigata Prefecture.The east of the Fuji River such as Tokyo and Sapporo is 50Hz, and the west of the Fuji River, such as Osaka and Fukuoka, is 60Hz (exceptionally, there is a 50/60Hz mixed area in Nagano and Niigata prefectures), which is still changing in 2018.not.
The difference in power supply frequency affects the use of home appliances.Equipment with a built -in inverter is converted from a DC (DC) to a required frequency exchange (AC) due to its function, so it is not affected by the difference in power supply, but has an effect on washing machines and microwave ovens.There are many products to receive.
If you use home appliances in different areas with corresponding power frequencies, there is a risk of serious accidents.For example, if you use a 50Hz -compatible washing machine in a 60Hz area, theoretically 1.It will rotate at double speed, causing a failure.In particular, microwave ovens and fluorescent lamps are dangerous, and in areas with different power frequencies, they cannot be used without replacement or adjustment of parts.
However, the AC adapter is an exception.The AC adapter (switching method) attached to the iPhone corresponds to a wide range of input voltage from 100V to 240V and a frequency of 50Hz/60Hz.Output as a DC of 5V/1A.Most of the AC adapters that support USB output are switching methods, so you don't have to worry about third -party products.
