Description
SINAMICS sine-wave filter for Power Module FSC base frame compatibility only with PM230/240/250 no base frame compatibility with PM240-2 and G120X 380-480 V 3AC 20.0 A Electrical filter SINAMICS sinewave filter for the PM 250 Power Module of the SINAMICS G120 modular frequency converter. Sinewave filters limit both the rate of change of the voltage (dv/dt) and the peak voltages across the motor winding. In a similar way to an output reactor, it permits connection of longer motor cables. Shaft currents are also substantially reduced. This makes it possible to run standard motors with standard insulation and without insulated bearings connected to SINAMICS. The voltage load on the motor winding is therefore almost at the same level as in direct on-line operation. Due to the very small rates of change of the voltage on the motor cable, the sinewave filter also has a positive effect on the electromagnetic compatibility (EMC). The sinewave filter is available in a three-phase voltage range 380 V to 480 V in frame sizes FSC to FSF. SINAMICS - simply my drive!
