For a motor to deliver a set HP with lower voltage it has to draw more amps.
But why ASSUME a RV A/C works that way??? Indeed my A/C tests years ago showed that the amps decreased with decreased voltage which leads to a vary obvious conclusion: The A/C was producing less cooling and/or air movement.
So you are saying that with lower voltage the motor speed drops?
Could be, although I was under impression that inductive motors regulate rpm by Hz and electric motors are rated at 110V for a reason.
When I have more time I try to use the meter Watts scale and play with different resistance extensions to compare.
Still the main fact is that ACs draw way less amp than they are rated by the factory.
