I need to provide a 10VAC power supply to a cirris cable tester and they said it was unbalanced. It is a three pin input with the center being neutral and each side is hot 10VAC but it is unbalanced. What do they mean by unbalanced? How would I wire that up? And is there a way to tell how to wire it in from looking at the device, I don't have the that power supply. Thanks Russ
Do you have a schematic of the unit?

Which model of cable tester are you using? There are 10 models here:
and this model use 110/220V ac or 9V battery:

It is a Cirris 1000 a discontinued model. But it uses the three pin
10VAC adapter. I emailed them and they explained what unbalanced meant to them. Just that the voltage could fluctuate a little from the 10VAC? No schematic available. So if I wire this with an adapter that comes from wall is it ground to 10VAC on each side or is it 10VAC between the two sides? Center tap to 10VAC on the left and center tap to 10VAC on the right.... or 10VAC from left to right then it would be gnd to 5VAC to the left and gnd to 5VAC to the right? More questions. I have damaged things by not being sure of stuff like this. Thank you."Uriah"

It's called an " RPWR-10 " power supply.
Its a SPECIAL design unit and with a special 3 pin plug.
