I am looking for a circuit diagram for a dual output, +15/-15 VDC, 1.0 amp power supply. The power supply has to be low voltage input, either 24 VAC or 24 VDC. I am trying to replace the 120 VAC power supply that we have used in the past. I can find lots of examples of 120/240 VAC power supplies that all use center tap step down transformers. However, I cannot find a 1:1 CT 24 VAC transformer to adapt those circuits to a Class 2 application.
I also cannot find a circuit that uses a low voltage DC input that produces a dual +/-15 VDC output. Thanks for any advice.
