Tips: which is better, 110V 60Hz or 220V 50Hz power supplies?
Some where I read that the major reason of using 50Hz rather than 60Hz is the climate temperature is higher and high frequency can heat up wiring. In the area where the temperature is low, but can not change the power frequency to 60Hz due to we need to change the standards of all electrical equipment. Personally I don't think the temperature is a major concern for the grid frequency, think about Philippines (60Hz, 220V), China (50Hz, 220V), USA (60Hz, 110V), Canada (60Hz, 110V) and most European countries are 50Hz, that's the history factor.

The frequency of 50Hz need the voltage of 220V-240V and frequency of 60Hz needs less voltage 110V-120V. The countries like Canada, US are using 60Hz 110V power supplies. So that all the appliances that use electricity require to maintain standards of 60Hz 110V. The major harm of 50Hz is that the AC power supply with 220V-240V can harmful to human. But the 60Hz supply with 110V-120V has less harmful for human.
