Need help regarding isolator wiring configuration.

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

Thank you for the help Jea48.
No there's nothing else printed on the unit save for that picture of the wiring and another sticker with only the model number and Topaz Electronics printed on it. It's the only one of these Ultra Isolators that I've seen that has no real details on it. It also it brand new/unused. Even the model number is something I could not find any info on and Topaz no longer makes these, sends you to another company for info that subsequently sends you to another company down the chain, and there was nothing they have info wise either. The only thing I know is that the inlet plug is 250v 20a, outlets are standard 20a and the weight matches up with 1.8 kva units from Topaz, MGE, and Daitron.The Topaz, MGE, and Daitron units that closest match up with this one are 120/240 input and 120/240 output compatible (all 240 volt units seem to be 120v input and output compatible) so I'm hoping that that means there would be no issues with using 120 input, but again there's no info on the unit at all.

Because of the 6-20P power inlet my guess is the primary input voltage is 220V
or 240V.
Secondary output voltage is 115V or 120V.

Connecting the primary to 120V will only give you around 60V on the output.
Make sure you check the output voltage with a voltmeter before connecting anything to it.

Thank you for your help. Only way to know is to test now.

Yes, Equitech makes models of 240v. I use a 120 model and wouldn’t be without it.
