Need help regarding isolator wiring configuration.


Hello everyone. I just bought and received a Topaz Ultra Isolator. Am I wrong in thinking so or is it already wired for balanced power? It looks odd in both the configuration and using both brown and red wiring jackets (which from what I understand usually are both used for hot wires), and the jumper from the third terminal to the second is odd to me. I'm not really educated enough in this matter to know what's going on here and there's not really a detailed wiring configuration like one seen on other models, only a single picture on the side that I've included.

The unit's input is a 6-20r input plug which needs to be replaced with a 20 amp iec inlet (due to the plugs being reversed on the 6-20r I have no idea if the hot and neutral wiring would be reversed as well compared to a usual 20 amp plug, but I'm assuming not?), and I wish to replace the outlets as well, but I want to make sure of everything before tackling this.

Hey @ptss 

It would be worth seeing if EquiTech or another balanced power conditioner provider had a 240V version. A step down transformer and balanced power transformer are identical except for the winding ratio, so it's a natural offering. In addition, those coils will slow down surges and reduce both common mode and differential noise, not to mention eliminate DC. 

Alternatively, use a wall mounted step down transformer, and something like a Furman Elite before your gear.  Furman may also have a 240-> 120V conditioner. 

Best,

Erik
Some marketing genius came up with balanced power to help sell conditioners.


Pretty sure it predates audiophile power conditioners becoming a "thing"

Its a terrible phrase because we do have balanced connectors in audio and so saying something is balanced immediately makes anyone aware of this think balanced power is similar.


There are some similarities, like the rejection of common mode noise. That preamp makers make a big deal of being "fully balanced" is not the fault of the tech, but of the hype. 

Personally, if I had the money, I'd run 240V from the entrance to the room, and then use a 2:1 balanced step down transformer.  This gives you an unbroken chain of balanced power, with high CMRR (common-mode rejection ratio) right up to the back of your electrical gear, along with a very low impedance path.  Since 240V transmission takes half the current of 120V, you have less of a voltage drop with long lines. A 10guage cable will seem to have half the impedance.  Though I'm on the fence about having such a great connection to the outside power without additional filtration.
