Description

Note
Refer to the layout diagrams and circuit diagrams provided on the enclosed customer CD for
the arrangement of components and interfaces, and for wiring.
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).
In the factory setting, the DC voltage is regulated to 1.5 times the rms value of the rated line
voltage.
Active Line Modules draw a virtually sinusoidal current from the supply system and cause
virtually no line harmonic distortions.
Active Line Modules are available for the following voltages and power ratings:
Line voltage
380 ... 480 V 3 AC
500 ... 690 V 3 AC
The power rating can be increased by connecting Active Line Modules in parallel.

DANGER
Rated power
132 ... 900 kW
560 ... 1400 kW
