Thanks Pieter, I should have thought more about it.
Don't forget B of the transformer. Mine have a given and measured B of 1.08 so I have to start calculating from 40V * 1.08 = 43.20 V.
Results f.e.g. in 43.2V * 1.414 = 61.08V - 1.2 V = 59.88 V (without load).

(Also my diodes differ from fact-sheet: given 0.72 V so I should have 1.435 V. But measured 1.54 V.)

Simulated load of the whole PSU with power-resistors results in a voltage drop of 5.7V.

So I would get 59.88 V - 5.7 V = 54.18 V if the mains-voltage of 230 V would not vary from 207 V to 253 V (ą 10%).


So theoretical I can get the min. value or the max. value:
min.: 48.76 V (-10%) / max.: 59.6 V (+10%).
