SINAMICS line choke for Power Module FSE 37 and 45 kW type rating based on I_N, can only be installed under G120, cannot be installed under V20. Electrical choke SINAMICS line choke for the Power Module PM240 of the modular frequency converter SINAMICS G120. Line chokes smooth out the current drawn by the converter and thus reduce the harmonic components in the line current. By reducing the current harmonics, the power components in the rectifier and the intermediate circuit capacitors are thermally relieved and the line feedback is reduced. Using a line choke increases the service life of the converter. The line choke is available in a three-phase voltage range from 380 V to 480 V and for frame sizes FSA to FSF as a base component. The cables to the Power Module are already connected to the line choke. SINAMICS - simply my drive.
