SINAMICS Output reactor for Power Module FSB base mounting possible Output reactor, load-side power component, for the modular SINAMICS G120 frequency converter. Output reactors are used to reduce capacitive compensating currents and voltage rate of rise (dv/dt) for motor cables 50 m (shielded) or 100 m (unshielded). The output reactor covers the three-phase voltage range from 200 V to 480 V 3 AC. For the frame size FSB, it is available as a substructure. SINAMICS – simply my drive.
