Active Line Modules can supply energy and return regenerative energy to the supply system.

Active Line Modules generate a regulated DC voltage that is kept consistent regardless of fluctuations in the line voltage (the line voltage must range within the permissible tolerances). Active Line Modules draw a virtually sinusoidal current from the supply system and therefore do not cause any harmful current harmonics.

A Braking Module and braking resistor are required only if the drives need to be decelerated in a controlled manner after a power failure – i.e. if energy cannot be recovered to the supply.
For further information about these components, see catalog D 21.3.
Up to 4 identical Active Line Modules can be connected in parallel to increase the power and to provide a redundant configuration.

Active Line Modules are available for the following voltages and power ratings:
