Hi, I have made the ( 0-30V ) [0.002A - 3A] lab power supply, which is almost ready.However I am confused as regarding the connection of the step down transformer 230/24V ( of a Local make in India- VEGAKIT).There are 2 thick single stranded copper wires on one side, while at the other side are 2 multi stranded aluminium wires.Which terminals are primary and secondary respectively? Ill be soon posting photos for your kind reference on the successful completion of this project.
