SINAMICS output choke for Power Module FSC, can be installed under the base. Electrical choke SINAMICS output choke for the modular frequency converter SINAMICS G120 and the compact converter SINAMICS G120C. Output chokes reduce the voltage gradient (du/dt) and the height of the current peaks. They also enable the connection of longer motor cables. The output choke should be mounted as close to the Power Module as possible. SINAMICS - simply my drive.
