Circuit diagram of 220 V single phase to 380 V three phase
220 frequency converter. Input single-phase 220, output three-phase 220. Three phase motor star connection to angle connection. If three-phase 380 is necessary, add a three-phase 220 to 380 transformer in the output of frequency converter. Alas, you are free
What is three-phase 380V and three-phase 220V? What is the difference between them?
Generally, there are two connection methods for the electricity generated by the generator, one is Y-type connection, because this connection is that two coils are connected in series with each other, so it can provide three-phase 380 and single-phase 220, while triangle connection is equal to that three coils are connected in parallel with each other, so it can only provide three-phase 220 or single-phase 220

- 16. For example, some fans need 12V voltage, but the current is only 0.5A, the power is 6W, some fans only need 5V, but the current is 1.2A Now the question is how to control the voltage and current. Another is how to change the 220 V AC into 5 V output without heating Add 100 points after explanation And then there is the adjustment of the fan gear. It should not use the rheostat to divide the voltage. Is it to directly lower the voltage to make the current smaller? The power smaller? Is it slow? I mean, how do I do it for a fan? The same power can have different voltages and currents. Of course, I hope that the voltage is high and the current is low. Can I make a 220 V voltage with 0.01 a current How does the AC / DC module work

- 18. What is the function of the fuse on the knife switch? 0 - 14 days and 23 hours to the end of the problem A netizen said [knife switch can't protect household appliances at all. General household appliances have their own protection functions (such as over-voltage protection, over-current protection and under voltage protection). As long as they are operated normally, household appliances generally won't break down. The failure of household appliances is generally caused by their own quality problems, aging internal components, wrong operation of users and lightning] If according to this netizen's opinion, I match the fuse tube to the knife switch, its size and thickness? I don't know if this netizen's opinion is reasonable?
