Hi, I am interested in buying a custom transformers from Alibaba website, however the manufacturer I am in contact with requires a following technical specs: 1) Primary coil inductance 2) Secondary coil inductance 3) Frequency 4) Wire thickness 5) Number of turns on primary and secondary The actual transformer core/model is already picked, now I just need someone to help me with the correct windings of this thing to work properly under my desired specs. The transformer core/model is EPC13 (ferrite core) as also seen on the pictures attached. My desired specs of the transformer are: Input voltage: approx 230VAC (50HZ) Output voltage: 9VAC Output current: approx 500mA Power: 4,5VA Pins: 2 input pins on primary 2 output pins on secondary So I need someone to help me to calculate required specs as written above (inductance, turns etc.) so that the transformer has the correct properties (230VAC to 9VAC (approx 500mA) Thank you for your replies.
