What does "three" in an induction cooker mean?
The 300V is at the input of the power, that is, the two ends of the large 5UF capacitor; the 18V drive voltage is at the third pin of the LM339 or the ZD1; the fan source is inserted; the 5V is the output terminal of the three terminal regulator in the machine. It is the basic guarantee to ensure the normal operation of the induction cooker.
According to the current level of energy efficiency products, the disk should be copper enameled wire, three energy efficiency is likely to be aluminum enameled wire, and if used for a long time, of course, the choice of copper wire cooling. The primary utilization rate of energy efficiency parameters is 90%, grade three is 86%, and there is a difference. The same power, 1 stage heating faster than 3, and more power saving, longer service life
Electromagnetic furnace level three should refer to three basic voltage bar. Namely: 300V/18V/5V.
