Howdy all! First post yay.
Okay. So I bought a small 3VA PCB mount power supply that steps down 240V to 2x6V. It has two secondaries and I'd want to hook it up as if it was a single secondary with a center tap. That way I can get dual rails(?) for a simple dual 5V DC supply.
Thing is, I have no diagram of the windings and I'm unsure which way the two should be connected. On the front it merely says [ 0 - 6V 0 - 6V ] roughly over the pins for the secondaries.
What could happen if I connect the two secondaries up so its not in phase?
As a side question: would I be able to get ±5V DC from two regulators (7805/7905) with just 6V AC input? I'm unsure what the minimum "input" voltage for these regulators should be above the required output voltage.
