In Reply to: RE: Given 140 watt dissapation...would a power transformer rated at posted by Caucasian Blackplate on July 1, 2015 at 19:02:49:
Transformer 1 would be .5A x 800v=400va rating
Transformer 2 would be .3A x 800v=240va rating
Total current draw would be ~175ma.
I currently have a custom Heyboer power transformer which is the .3A@800v option....but that puppy gets really hot after 90 minutes.
Maybe upgrading to the Hammond 378cx @ 465 va would run cooler...but how much cooler?
