Power frequency in some countries is 50 Hz, and in others it's 60 Hz. If I want to use a device that was made for 60 Hz, in a country where the power frequency is 50 Hz, what can I do?
I'm looking for commercial invertors or ways to build the circuit myself.
most of the devices will work without any problem. The major concern is if you a trying to use some AC electric motors, because their speed depends on frequency. If the voltage needed is the same you don't have problem to conect any Audio/video/PC equpment in the mains- slightly difrent frequency will not make difrence in performance.
Use a battery charger rated for source power (ie 220vac 50hz) connected to a battery (use a "smart" charger). Run an inverter rated for your output power (ie 120vac 60hz). Bonus... you get a UPS.
it is no need to convert in most cases.but sometimes a elec clock use the power AC frequence as conter,it will cause problem.if so,it is difficult to convert,it is too expensive.
hope helpful.
