Circuits of multi windings transformers

Circuits of multi windings transformers
a) primary voltage (V)

schaltung_mehrwicklungs_trafos2
b) secondary voltage (V), c) Brücke

Example:
If the transformers will be connected to a 460 V rated input voltage the terminals 1.4 and 1.8 must be connected.
If the transformers shall have 230 V rated output voltage, connect the terminals 2.3 and 2.4.
