Lovetube,
Power transformer design is not difficult nowadays. PSUD2 is quite enough. Design your own PSU with PSUD2 and see the current peak value through the secondary (It1). This is current value for calculated thickness of the secondary wire.
Most transformer cores today come from China or India. Hard to find a precise and accurate data for these cores. Therefore we recommend to take the value of peak current through secondary (not sinus value).
Your 30 mA requires about 100 mA (C input PSU) through the PT secondary. With L input PSU, current peak wil be about 50 mA (or so).
You will see exact value after PSU design in PSUD2.
Best diying.
