I am using single phase step down transformer of voltage in primary 230ac to voltage on secondary 18v ac. But I don't know what is its mA rating on secondary side. Also help me to calculate mA rating for digital circuit which contains 3 led, 3 led seven segments, 1 microcontroller, 1 30A 12v relay. I want to drive this circuit using step down transformer.
