While cleaning up some newly acquired 12 KV, 60ma NSTs, I noticed something odd about the VA rating. Looks like 2 of them list 400 VA. The others list 720 VA which makes sense when you notice that 12000 * .060 = 720. My 15KV 60 ma units list 900 VA which also makes sense. I am guessing that the 400VA has something to do with power factor??? Does anyone know what's up with this? Happy Coiling, Ross Overstreet Huntington Beach, CA
