B buju357 New Member Jan 1, 2011 #1 Hi all as the title says , if a transformer is rated at at 80VA 0-12/0-12 , All primary windings are rated at 220/240Vac , what would the max amperage output be ? also what is the formula to calculate the amperage. here is the link to the transformer: Toroidal Transformer, 80VA 0-12/0-12 (AMZ73G) [AMZ73G] - R242.05 : Zen Cart!, The Art of E-commerce thanks

Nigel Goodwin Super Moderator Most Helpful Member Jan 1, 2011 #2 VA(W) = V x I So 80W / 24V = 3.33A So either 24V at 3.33A or 12V at 6.66A.
