5.4 Active Line Modules including Active Interface Modules
Active Line Modules can supply motoring 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).
With the factory setting, the DC voltage is controlled to 1.5 times the rms value of the rated
supply voltage.
Active Line Modules draw a virtually sinusoidal current from the supply system and cause
virtually no line harmonic distortions.
Active Line Modules are suitable for connection to supply systems grounded at the neutral
point (TN, TT) and ungrounded power systems (IT). The following voltages and power
ratings are available:
Line voltage
380 to 480 V 3 ph. AC
500 to 690 V 3 ph. AC
The power rating can be increased by connecting Active Line Modules in parallel.
