From the box photo (found these clean images on the net but the same as the unit I have) it appears to be a 240v - 220v transformer which operates at 2KVA.
I do need another 220v-120v step down transformer at home, but I don't think this will do the job. Many thanks for any assistance.
PS: I've spent an hour scouring the internet for a PDF manual or other technical info via google translate with no success :(
