Hi,
This seems like a simple question but I've had a surprisingly hard time finding answers from googling.
I have a situation where I need a power supply that outputs the following voltages (in order to replace a legacy power supply that provides said voltages):
16V
12V
5V
-5V
In the past I've always just grabbed an off-the-shelf solution that provided the voltages that I needed, but the closest that I think I'll be able to find for the above voltages would be something like this: https://www.amazon.com/gp/product/B005T9PSKO/
I'm wondering if I could just take a separate 5V wall wart, reverse the polarity on it and get -5V. I'm assuming there is probably a reason this wouldn't work, but I'm not sure what it would be. Can anyone help educate me?
