Example
A three-phase QUINT POWER 20 A/ 3 · 400V power supply unit is connected to a free
output of a distribution box via a 75 m (246 ft.) copper cable with A = 2.5 mm 2 (14 AWG).
A voltage of U L ? = 3 · 400 V AC is measured at the distribution box.
How high is the AC voltage at the input of the power supply unit?
