Q. Is it possible to configure these switch mode PSU's in such a way to get +15V and -15V at the output? I am assuming that I would need to buy two PSU but how would they be wired? Thanks
A. Thanks for your enquiry Dave. The only way you can do this is by reversing the polarity of the one of the outputs which will give +15 and -15 with respect to the common negative or earth line.
