can u use a 220v to 12v transformer step down transf, switch the primary as the secondary, and vice and make it a 12v to 220v transformer.
This is a 12V center tapped transformer. Yes, you can take 2 transformers, and connect the secondaries together, apply 220V on one, and get 220V back on the other side. One would be a step down, the other a step up. The transformer doesn't care which way you go. The 220V output will be limited to the rating of the transformer. Say you have a 100VA transformer. If you divide the VA rating by the voltage, you will get the amount of current. In this case 454mA. On the 12V side, you can determine current as well. 100/12 8.3A. That is how much you would have to supply to get full output.
confident. you will incur larger losses than if the transformer became particularly designed for 220 V, inspite of the undeniable fact that it is going to in all possibility be insignificant. be conscious, inspite of the undeniable fact that, that attempting the different (making use of a transformer designed for 220 V in a 440 V circuit) might _not_ paintings, because of the fact the conventional might overheat.
It is a 12V center tapped if you input 220VAC. If you put in 110VAC, then it is 6V center tapped. Generally, if you have a 12V-0-12V, it is center tapped and you can generate 24Vdc out of it, if you use without center-tap wire.
