Self-commutated, pulsed rectifier/ regenerative units Active Front End AFE
The design of the power section of AFE inverters is identical to that of the standard inverters of the SIMOVERT MASTERDRIVES series. It is therefore not necessary to keep special spare parts for AFE inverters.
The CUSA control board makes a standard inverter into an AFE inverter. The power range is 6.8 kW to 1200 kW with supply voltages of 3 AC 400 V, 500 V and 690 V. For power outputs of > 250 kW i.e. all chassis units, a special sine filter calledClean-Power filter is necessary.
