Smart Line Modules are non-regulated rectifier/regenerative units. The infeed occurs over a diode jumper, while stable, line-commutated regenerative feedback takes place via IGBTs with 100 % continuous energy regeneration. An autotransformer is not required for regenerative feedback.

The regenerative capability can be deactivated.

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

The power ratings can be increased by connecting up to four identical Smart Line Modules in parallel.
