Variac transformer

Good quality item. Good price. It came quickly. I expected these to be more expensive. There was no reason to make do without one for so long. Thanks guys.

1000VA Isolation Transformer, 117VAC to 117VAC

This is a true technician's isolation transformer that does not carry the ground or the neutral through from the source. This is a crucial difference from most other isolation transformers on the market. It's a joy to have the flexibility to safely establish an arbitrary local ground reference anywhere in an active circuit for *one* oscilloscope probe (note that additional probes must use that same ground reference point to avoid the risk of a short circuit and personal injury or damage to the oscilloscope or the UUT). This product uses a toroidal transformer that is quiet, efficient and powerful. I'm pleased with the isolation transformer, the customer service and the shipping department who expertly and carefully packaged this heavy unit to prevent damage in transit.

Works great. Just a little concerned that the cord is a little flimsy so I added a 4ft heavier extension cord. Hope that’s OK
