Good day all!
I'm having a brain cloud, and I can't seem to be able to figure this out for sure. Maybe I just need someone to confirm what I am thinking:
I'm ordering a power transformer. The datasheet states the secondary RMS Rating as such:
Parallel VAC 8.0 @1.600 Amps
Series VCT 16 @ .800 Amps
So here is where I get fouled up. I'm working on a dual polarity power supply, regulated down to 5VDC positive and negative. Using a center tap would give me 8Volts for each regulator (7805 & 7905) correct? Because the potential is measured between the center tap and either side of the secondary?
So if I were to run a transformer using parallel secondary (No center tap) I would be getting 4 volts for each regulator, because the potential is then measured between the secondary leads, without a center tap?
So if I use a hot ground, this would then give me 8 volts for each regulator?
So for this transformer, in order to obtain 8volts for each regulator, I either need a center tap, or employ the use of a hot ground. Correct?
Apologies If this sounds confusing. Maybe I can state it in a different way to make more sense?
