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.
