I know the basics of transformers and one thing I have never understood is the specification of primary and secondary voltages. By theory, the 2 parameters of importance is the transformation ratio and the VA rating right?. But then why do transformers have specified primary and secondary voltages?
I have a 120 VAC primary voltage (to 24VAC in sec.) transformer but my supply is 230VAC. So, Can I connect two such transformers in series (in the primary section) to make sure the specification voltage is not exceeded?
But what is the significance of these voltage specifications? Can I connect 230VAC directly and just make sure the current in the secondary output does not exceed the VA rating? Would that work?
The problem is I have two 120VAC to 24VAC transformers and my supply is 230VAC. So can I connect the primary in series and the secondary in parallel to achieve 230VAC to 24VAC transformation.
