heaveno,

The document of the QSXPS power supply says that a transformer with voltages in the 18v - 24v AC range is needed for an output of +/-15VDC
This looks like a huge margin to me.
What is the minimum transformer AC voltage required for an output of +/-15VDC?
Same question for an output of +/-12VDC.

Thanks for your help

Olivier

IF you have the resistors in series you will lose some voltage but on the other you'll get a smoother raw voltage. You must have approx. more than 5 volts more in than out and in is here after the resistors. 15 VAC for 15 VDC out is on the edge.
