Can I run 220-230V 50Hz appliances (built-in ovens etc...) in a 220-230V 60Hz country?

Question

Is there a risk if they have digital displays/controls?

Answer 1

Usually the display will not have a problem, since it anyways runs on an internal low voltage AC or even a DC supply.

However, the performance of the equipment itself might be affected, if it is designed to operate on 50Hz and you use it on 60Hz.

Answer 2

Most appliances are designed for 50 or 60 Hz operation. However, some motor-driven appliances may not work properly. The higher frequency of 60Hz will drive the motors faster and any internal timing that is based on motor speed will be wrong. Examples of the latter are (of course) old-fashioned motor-driven electric clocks, timers on wash machines, etc. Most modern appliances use electronic timers with internal clocks that are not affected by line frequency, but there is no way to tell for sure. If the appliance timer is a rotating dial, there is a good chance it runs from a motor. However, if it has digital display and controls, it almost certainly will not be affected by the line frequency.

Answer 3

It's extremely likely that you can, because the digitial display part is usually run off a transformer/rectifier which changes the supply to low voltage direct current - this will be the same no matter what the input frequency.

But it depends on the design, so you really have to look at the manufacturer's specifications.
