I got three 300VA toroid transformer from my father's junk box with a primary AC 117VAC. Here in my country we use 220VAC main AC. How to calculate windings for primary and secondary to convert this transformer primary to 220VAC and 18V-0-18V secondary?
can someone help me for calculation.
the easiest way is to use a step down transfmormer of course.
thanks |

Use two of them at the same time and wire the primaries in series.
What are the specs on the transformers? Center tapped? Output voltage? |

sorry it was a 180VA transformer if my calculations correct,
primary is 117VAC, and 2x15VAC secondary 6Amp. |
