All of the countries in the world are powered via AC supplies from the mains, but the frequency ranges can vary from country to country. For instance, in UK the frequency is 50 Hz and in USA it is 60 Hz. The voltage ranges are also different as there is a voltage of 250V in the UK and 120. .
Power converters come in several types which you can choose from. Talking about Step down Converters first, they operate by converting a higher voltage to convert to a lower voltage. .
One major advantage of converting high voltage AC supply to a lower voltage is the reduction in power losses. This is due to the fact that when your winch is actually operating on a high voltage AC, it will be withdrawing a much smaller amount of current to achieve. The converter should be capable enough to bear twice to three times the wattage that is required to power the winch, so that you can operate it on the safer side. Nobody would want to repeatedly replace their converter due to power surges. [pdf]
