A couple updates: I finally got around to unplugging everything from my mainstay the 5KVA-31 to see how it would compare to the 5KVA-69... -

The 91905-69 has the same 0.0005pf capacitance as the -31 and -32 transformers and the exterior construction is the same as well. The...

Mmkaza replied to the thread Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power.Excellent - many thanks; a good confirmation that Topaz is doing its job pretty effectively. If you don't mind, what is the pF & CMNRR...

I bought an EMI noise tester to see how the Topaz -69 does. The pics below are with the house air conditioner off. With it on it was...

If the power draw tops out at 700W then an 2KVA IT should be fine if the UPS is t replenish itself. If it needs to replenish itself then...

Mmkaza replied to the thread Topaz Low-Capacitance Isolation Transformers - for Affordably Clean Power.Many thanks @zilch0md for your reply. I agree, quantification is not easy - but your view that an IT with 0.001pf is pretty good - will...

@mkaza I’d think the best sound quality would come from the wall/IT/component combination but since you already have the UPS it won’t...

Hi mkaza, I wish I had an equation for calculating the maximum frequency at which NR is "effective" vs. the pF capacitance rating, but...
