Does anyone have power supply circuit that has 0~+/-30v dual output ports function and can be adjusted in voltage and current output?
I'd like to implement one that just for my hobby.
Please offer it as my reference.
Appreciated.

Build two of those and you will have a laboratory-quality +/-30V(at)2A adjustable power supply ..

It is single power output.
I need dual power output.
Thanks

Create a DUAL supply power supply by using bridge and a center tapped transformer, then make use of POSITIVE and NEGATIVE ADJUSTABLE Voltage Regulators.
For Current Variable Adjust, I haven't used one for my circuits, it is as good as a current limiting regulator.
