Transformer not the same


Can I use a 240 / 24V 40VA transformer in place of a 120 / 24V 40VA transformer?

Re: Transformer not the same


If your question is:
Is the output from a 240/24V 40 VA transformer supplied with 240V power the same as the output from a 120/24V 40 VA transformer supplied with 120V power?, then the answer is yes.

If your question is:
Is the output from a 240/24V 40 VA transformer supplied with 120V power the same as the output from a 120/24V 40 VA transformer supplied with 120V power?, then the answer is no.

In a simple single phase voltage transformer, the ratio of output voltage to input voltage remains constant, so in the second scenario above the output voltage would drop in half to 12V.

Re: Transformer not the same


The only way you can use it is if you connect it to 240 volts instead of 120 volts.
