Not sure of these step up/down transformers will do it for you. I am using a 2000 watt transformer here in the US with my Swiss made coffee machine and it is awesome. I also plan on using a 1500 watt for myGerman built 230 volt audio equipment.

When it is on and at idlde with no current source on or in use, the 2000 watt transformer only used 6 watts as measured with my power usage meter. When the coffee machine was making coffee or when it initially turned on, it surged up to 1450 watts. This transformer is also very quiet. I was stationed in Germany for many years and I used many a stepdown transformer for US made equipment. I can tell you from experience, this is really a quiet transformer. I only hope it will work for you.
Good luck,
