ACSM1 power ratings for DC connection
The power unit diagram with related power ratings is shown in the following
figure.
Average rectifier power P
rec,ave
P
rec,ave
is the
maximum average DC power that an ACSM1 input bridge can
supply. The actual average DC power taken from the input bridge should be
lower than this value in any 3 minutes time window.
Peak rectifier power P
rec,max
P
rec,max
is the maximum short time DC power capacity of an ACSM1. This is
the maximum DC power level for input bridge and DC connection terminals
during 1 s.

values are defined at 540 V DC link voltage level, which corresponds to
the nominal 400 V AC supply voltage
U

. In case of other DC voltage level
(
