Smart Line Modules are unregulated infeed/regenerative feedback units. Like the Basic Line
Module, they supply energy to the connected Motor Modules, but unlike the Basic Line
Module, they can feed back regenerative energy. The infeed occurs over a diode jumper,
while stable, line-commutated regenerative feedback takes place via IGBTs with 100 %
continuous energy regeneration.
Under full load, the DC link voltage is higher than the rms value of the rated supply voltage
by a factor of 1.30, and under partial load by a factor of 1.32.
Smart Line Modules are suitable for connection to supply systems grounded at the neutral
point (TN, TT) and ungrounded supply 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 Smart Line Modules in parallel.
