Please allow me to translate for the forum folks...
By "tensions", I believe you mean "voltages".

It says it is 105-125VAC 50/60Hz and two input taps (110 or 120). My guess is that the 110V tap is 105-115, and the 120V tap is 115-125. The output voltages are not given.

The schematic can be found on this website:
