Functions and features
ƒ
The 9352-E brake chopper is designed for operation at brake
resistances >=27 Ohm with a DC-bus voltage of 765 V.
ƒ
The rated data applies to a brake resistance with 27 Ohm.
The 9352-E brake chopper can conduct brake resistances
from 18 Ohm if the maximum braking times / application
times according to the Operating Instructions are adhered
to. At 18 Ohm and 765 V DC-bus voltage, the maximum
running time is 1 s and the maximum power 32 kW.
If the running times are exceeded, this can result in a brake
chopper failure - see EDBMB935X Operating Instructions.
