Smart Line Modules are uncontrolled rectifier/regenerative units. The infeed circuit comprises a diode bridge, while the line-commutated regenerative feedback circuit with immunity to inverter commutation faults comprises IGBTs with 100 % continuous regenerative power. An autotransformer is not required for regenerative feedback.
The regenerative capability can be deactivated with a digital input.
Smart Line Modules are suitable for connection to grounded TN/TT and non-grounded IT systems. The following voltages and power ratings are available:
Line voltage | Rated power |
---|---|
80 … 480 V 3 AC | 250 … 800 kW |
500 … 690 V 3 AC | 450 … 1400 kW |
The power ratings can be increased by connecting up to four identical Smart Line Modules in parallel. For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.
