6.9 Braking resistor
In addition to the supply modules, STOBER offers braking resistors in the various sizes and
performance classes described below. For the selection, note the minimum permitted braking
resistors specified in the technical data of the supply modules. In the event of a fault, such as a
defective brake chopper, the supply module must be disconnected from the power supply.
