electing an AC motor drive that will be
able to supply all the power and
flexibility required without over- or
Sunder-dimensioning can be a
challenge. A careful choice ensures the efficiency
and reliability of equipment, systems, and
production facilities. The new C2000 Plus Series
of vector control motor drives from Delta offers
improved overload capacity, making these drives
an outstanding choice for more applications than
ever before.
There are AC motor drives that perform well in
general-purpose applications and others for more
