Hello friendsi need transformer for my project (regulated power supply) i need 220 50hz ac input and 3 volt 50hz out put ac voltage is this possible.what is wattage of that rating transformer?thanks a lot
Watts rating of the transformer depends on the load. If you have a 10 amp load, for example, that is 10x3 30 watts, so you need a transformer a bit larger than that, say 35 or 40 watts. PS, you will probably not be able to find this transformer available. You may have to settle for a higher voltage, say 5 or 6 volts and reduce it by some other means, or by rewiring the transformer. .
not enough information wattage is determined by the load demand and the efficiency of the transformer all we can tell for what you provided would be the step down windings turn ratios what is being powered on the 3 vac side of your project?
