Active Line Modules are regulated rectifier/regenerative units. They can supply energy to the DC link and return regenerative energy to the supply system.

In contrast to Basic Line Modules and Smart Line Modules, Active Line Modules generate a stabilized DC voltage that is kept constant despite fluctuations in the line voltage (the line voltage must remain within the permissible tolerance range). Active Line Modules in combination with an Active Interface Module draw a virtually sinusoidal current from the supply system. Almost no harmonics occur.

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. when energy cannot be recovered to the supply).

Active Line Modules are suitable for connection to grounded TN/TT and non-grounded IT systems. The following voltages and power ratings are available:
