question

If a manufacturer describes a power supply transformer as providing a secondary voltage of 24 volts when connected to a 240 volt mains supply, do you think they are referring to the full load or no load secondary voltage?

 

[Riggy]

No load, although the drop should be marginal at full RATED load, an overload would naturally drag it down.

My expectation is for the transformer's voltage specification to be good up to full-load.

id expect the voltage to be at the rated load
