Line modules
Convert the three-phase supply into a DC voltage for the DC link.
● Smart line modules
The smart line modules generate a non-stabilized DC link voltage and are capable of
regenerative feedback.
● Active line modules
The active line modules generate a stabilized DC link voltage and are capable of
regenerative feedback.
● Basic Line Modules
Basic Line Modules generate an unregulated DC link voltage and are not capable of
regenerative feedback.
Motor modules
● Convert energy from the DC link for the connected motors with variable voltage and
variable frequency.
