Earlier induction cooktops used high-frequency ones, such as the KS4 series. I was doing national brands, using IR a chip, this chip is very close to the KS4, but to do some fine-tuning in the drive resistance. The latter various induction cooker manufacturers based on the cost, it limits the frequency. Used KT4. I think it is very unkind. This is why people say the Japanese rice cooker cooks good rice?
Because the frequency is limited, the power is small, labeled 15KW, in fact, 12KW or less. It takes a little more time to make a meal, and the customer is not aware of it. But there must be a difference in taste and fire. Of course, also in the acceptable range.
It is recommended to use Starr. Fuji's are fine, not the module does not work, but you will not use it?
