Hi All! What determines the number of turns on the primary side of a Transformer? for instance I want a step down transformer from 110V to 60V witch would be a 2 to 1 turn ratio .I could get that ratio by 100 turn on the primary side and 50 turns on the secondary side or 50 turns on the Primary side and 25 turns on the secondary side. I am sure the permeability of the core, and the out put wattage hast to be known and probable several other factors. any help would be appreciated Thanks in advance brent.

Basically The Frequency, Permability and Voltage will Determine the Primary Turns. (or Inductance Value)
A Primary Inductance Value of 600 to 1000 mhy should be OK for your 110VAC input. (DEPENDS Somewhat on Core Size.)
The Wire Size and Core Size will determine Maximum Currents.
