Hi Jason,

Are you requesting a datasheet for the transformer, or how the specifications for this transformer were determined?

FYI, it is made by PMU: http://www.pma-italy.com/prodotti/ricerca_E.asp .

Hello Jason,

The transformer has been developed by an Italian manufacturer. I attached the datasheet with the details of the dimensions, number of turns for each winding and diameter of the wires. Since the text is in Italian, I translate the most important words:

T --> Terminal pin is present, connected and cut.

L --> Terminal pin is present but not connected

X --> Terminal pin is present and connected

O --> Terminal pin is not present

"Posizione terminali (visto da sotto)" --> "Terminal pin position (bottom view)"

"Rigidita'" --> "Isolation voltage"

"AVV" --> "Winding"

Nspire --> "Number of turns"

"TIPO" --> "Type"

I hope my explanation is sufficient. Please let me know also if you can read the datasheet or it has not been attached.Transformer E20_12W.pdf.

Best regards,

Roberto

Hi Joey,

I attached the datasheet of the original transformer. Even though some text is in Italian, I believe technical data should be easy to understand.
