Can an induction heater for domestic use (2000W) of 220V/60Hz be used efficiently with 230V/50Hz power supply? Answered

I purchased one Induction heater (2KW) in Korea where the supply voltage is 220V/50Hz. I want to use this in India where the supply voltage is 230V/50Hz. Can this be used?

Induction heaters don't work at mains frequency, but a lot higher, so there are active power electronics inside - it will look like a switch mode PSU. High voltage rectification - and then choppinng into a transformer which is partly the induction heater element.

Dear Steveastrouk,
I will request you to kindly look at the comment given by Aborah. If his opinion is correct, then I understand that the instrument will have reduced life due to high current passing through the coil. Please tell me whether the active electronics will be able to regulate the current (may be at the cost of low efficiency) so that the induction heater will work normally at 50Hz frequency. If so, advise whether I can use the instrument at 230V/50Hz.

The active electronics should control the current.

http://theinductionsite.com/how-induction-works.shtml should answer our questions (regulating electronics is there). The http://www.youtube.com/watch?v=QPd963cCeec may be a bit simplified. (btw, I deleted my earlier comment by mistake)

Dear Aborah,
The link is very useful. However, answer to my specific question is not there. I follow with the logic that regulated electronics should take care of the change in frequency. Steveastrouk also gives the same logic in this case. If you find answer to my specific question, please paste it here. Thanking you once again.

Yes, I agree with 10% voltage fluctuation. But I am concerned with the change in frequency (60Hz to 50 Hz). Kindly give your reply in this aspect

Yes, not a problem. A mains powered design is specified for +5 /-10% of the nominal plated voltage
