1. Read the transformer’s secondary winding rating (printed or tagged on the transformer case). This should give a rating such as 5V, 500mA.
Multiply the voltage times the current to receive the VA.
Example: 5V times 500mA (or 0.5A) equals 2.5VA
2.Convert the secondary winding VA value to the primary winding VA rating as the equation VA (Primary) equals VA (Secondary) or VA (p)=VA(s)
For example of a 2.5VA secondary, if the primary voltage is 120V the current will be A (p) = VA(s) / V(p). Giving A(p) = 2.5 / 120 = 0.020833(roughly 21mA).
This is the calculation for a single input winding/single output winding transformer.
3. Add the separate VA ratings for a transformer with multiple secondary windings.
For secondary winding 1 = 5VA at 500mA
Secondary winding 2 = 24V at 100mA
Total Secondary VA = ( 5 X 0.5 ) + ( 24 X 0.1 ) = 4.9VA
Primary VA will still equal the total secondary VA.
