SINAMICS Output reactor FOR POWERMODULE FSB 3AC 380V-480V 18,5A Electrical reactor SINAMICS output reactor for modular SINAMICS G120 inverters and compact SINAMICS G120C inverters. Output reactors reduce the rate of voltage rise (dv/dt) and the magnitude of the current peaks. Further, it allows longer motor cables to be connected. The output reactor must be installed as close as possible to the Power Module. SINAMICS – simply my drive!
