The way I understand it there is a motor run cap inside that regulates the power through a resonance effect. They can hold outut voltage rock stable with anything between 90-140 input...Heck they can even hold stable output voltage through a missing cycle or two of input.
I see new ones are stupid expensive...I got all of mine by haunting Hamfests and antique radio swapmets...I don't think I paid over $25 a pop for mine. Every one of the 4 I've got was a good purchase, and I'm still lookin for more.
The advantage of a CVT is there is no switch mode supply to potentially generate RF hash on the line...Also fewer parts means less to go wrong. |
Wow that's impressive it can hold stable of a missing a cycle or 2! Probably more efficient than the ac-dc kind as well. Really don't want any RF hash on the line as well. It is a shame they are so expensive. I will have to keep an eye out at the swapmeets and perhaps I can pick up one for a better price.
