Transformer capacity is rated in Volt-Amps (VA) which is generally the same as wattage 

(Watts). 

Most loads are labeled with their proper operational voltage (Volts), current (Amps), 

frequency (Hz), and wattage (Watts or VA). When you need to design a transformer,

we must know the mainly below parameters to be customized:GREWIN's Custom
