Variable Transformer 10 Amp (1000 Watts); 0~130VAC Output w/ISOLATION

It was carefully packed, arrived intact and works perfectly..

An autotransformer (variac) it is, capable of working with loads up to 1000 watts but it is also a isolation transformer to give safety to the worker and equipment.
Well built with only a few minor areas that others have commented concern which I yawned.
It came in securely in an extremely triple box system to assure the 23 pounder arrived without incident.
These folks have a winner. I am very pleased with them and their product.
