Picked up a nice and rather compact isolation transformer. The previous owner had upgraded it from 300VA to 500VA with the biggest Ring Transformer I've ever seen. My old isolation transformer only managed 200VA and was struggling in some circumstances, so it was time to upgrade. Unfortunately, like most modern Isolation transformers, the Earth wire is connected through, making it not fully isolated, but that will be modified as soon as I have time. Never heard of the maker Renesse, nor could I find anything online about the device.
