Title: Transformer Related Question ??
Post by: magnetman12003 on August 08, 2015, 03:30:12 PM
I have a hi frequency  transformer with a secondary of 2200 ohms and a primary of 25 ohms.

Notice the 88 to 1 ratio.     I have a power supply that puts out 1232 volts AC and wish to see 14 volts AC output.  Notice the 88 to 1 ratio again.

Question:  Can I connect the  transformers secondary to the power supplies 1232 volts and see 14 volts AC out of the primary?

The question is a learning curve for me.

Transformer impedance changes as the square of the turns ratio.  Voltage changes proportionally to the turns ratio.   88:1 impedance is about 9.4:1 turns ratio.

Would that mean 1:1 transformer is always 1:1 ?

Ignoring losses, yes.

Those values are actually the transformer specs, not what you measured with a multimeter, correct? If so, then all is good. Also, if its a HF transformer, make sure you use it only at HF.

Do you have a problem with molten enamel?
