Hi guys,
I have a power supply that can only take positive voltages but I would like it to be able to take negative voltages. To achieve this normally, I have to manually take out the positive and negative pins and put them on the negative/positive input terminals on the power supply respectively.
I would like to have this done automatically using some sort of analog multiplexer where it takes the two positive/negative pins as inputs and has two outputs that go into the positive/negative terminals of the power supply. Ideally, a signal from the PC would provide the switch (high/low).
I'm more of a software guy so my electronics knowledge is a little basic.![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I figure I would need some sort of analog multiplexer with tristate. I also am a little worried of the potential voltage loss that may occur in the multiplexer circuitry.
Since you guys are way more pro than me with this sort of thing, I was wondering if somebody could please give me advice on how to approach this?![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thanks in advance!
