    230V/50Hz to 110V/60Hz converter?

    Thanks again Baluncore. It would not be very feasible trying to sell a 110V appliance in a country that supplies 240V, nor ship it to a country that supplies that due to the weight/bulk of the item, but thanks for the suggestion. Just a few more questions: I have a 600VA, step down transformer...

    230V/50Hz to 110V/60Hz converter?

    Hi Baluncore, Thanks for chipping in. I'd like to think that it wouldn't be a problem, but most sites I've seen calculates the additional current drawn to be much higher than the 17% difference in frequency. That's the "fact" for me. Do you have a better reason than "speed control need not be...

    230V/50Hz to 110V/60Hz converter?

    Hi Averagesupernova, I'm pretty sure it's an induction motor as it says on the product specifications. fyi, it's a Breville BFP800XL food processor - http://www.brevilleusa.com/sous-chef-food-processor.html So it seems that as long as I keep the V/f ratio the same, it should draw the same...

    230V/50Hz to 110V/60Hz converter?

    Can someone explain why using a 60Hz induction motor on a 50Hz mains supply will generate more current as the 2 links claim? I understand why the motor would spin slower as a directly correlated to the mains frequency, but I don't understand why it would draw more current. Also, I'm assuming...

    230V/50Hz to 110V/60Hz converter?

    Thanks jedishrfu. I actually read the 2nd link. It suggested that doing that would cause significant loss of power and possibly internal supply voltages that are no longer regulated though. Windadct, I checked the product tech specs. The manufacturer however did not specify if the appliance...

    230V/50Hz to 110V/60Hz converter?

    Hi, I've just purchased a 1200W food processor with an induction motor from US that requires 110V, intending to use it locally where the mains supply is 230V/50Hz, thinking I could just get away with a high powered step down transformer. However, after researching, it seems that the motor...

    Choosing and using chip ferrite beads for EMI suppression

    Hi, I didn't want to post another thread since I have a similar question. Sorry for threadjacking... What about the usage of chip ferrite beads for signals rather than power? What kind of signals need to be filtered for EMI suppression, and how do I choose what kind of chip beads to use...
