Will this three phase transformer do the job?



My son has jsut bought a good sized NC router for use in his manufacturing operation.

The new machine draws about 40 KVA maximum load and needs a 480 volt three phase delta supply.

His shop has only 208 volt three phase Y power available.

This transformer on e-bay looks to us like it could be used to get him the 480 volt delta supply he needs when driven by his shop power:

I've never gotten very involved with three phase machinery power and don't want to tell him to start bidding on that transformer (or similar ones) without checking here on rcm to see if there's other important things to consider when using three phase power transformers for this kind of application.

Thanks guys,

Jeff
