I see transformer specs listed as 360-0-360 for a secondary of a power transformer. I understand that this means there is a center tap, and with a full wave rectifier this comes out to VRMS * 1.4142 = 360VAC * 1.4142 = ~509 VDC (assuming smoothing caps etc, beyond the scope here)
But if you remove that center tap, then you could say the transformer is 360-360, or 0-700, correct? So if you then used a full wave bridge rectifier on 720VAC, you would have 720VAC * 1.4142 = ~1018 VDC.
Obviously I'm missing something crucial here about how transformer specs are defined. I certainly don't want to be off by a factor of 2 when I'm getting my transformer manufactured.
