Re: {Collins} [Bulk] Re: [Bulk] Re: 30L-1 - convert between 115V and 230V

Gentlemen,

remember that the losses in the transformer winding are:
P=I squared  x  R

which means as an eample:

1)  for R=100   and  I=10   the P= 10000 W
2)  for R=200   and  I=5     the P=200 x 25 = 5000 W .

This means that losses (heat) under 115V are much higher than at 230V .  
This is due to the current that is squared ...  ... non linear ...
