See the instructions given for the cabinet-installed multidrives.
Diode supply modules ACS880-304LC+A019
The supply modules do not have input chokes. For this reason, dimension the supply
transformer according to the supply unit apparent power (
S
n
), and make sure that the supply
transformer impedance is suitable for the supply unit. The transformer reactance X
k
has to
be at least 4% and the transformer nominal apparent power ( S
n
) must not be more than 2
times the nominal apparent power ( S
n
) of the supply unit in question.
