Re: Transformer drawing 1 amp

On the case(of the charger, not the transformer) it says

Input: 120VAC 50/60 Hz 2.8 Amps
Output: 12VDC 15 Amps

This is why I assumed it was 15 Amps.

Now since the ratio is 10:1 that means that it would draw a max
current of 1.5 Amps at full load on the primary due to the load. Since
I'm drawing 1A without any load this is about 2.5A on the primary at
full load. So it seems to work out. I guess this transformer is a
current limiting one.

Now if I understand a current limiting transformer it is made in such
a way as to limit the max current drawn on the primary? It does this
by sacrificing power? So at full load of 15A the primary will be
pulling much more current than it should but if I tried to pull 20A it
would not let me? Sorta like some sort of over current protection? A
"normal" transformer would not get as hot but it seems to be ok for
this one?

Thanks,
Bob
