The braking resistor REOHM 154 protects the machine from a voltage rise in the intermediate circuit, if an electric machine operates as a generator (Electromotive brake). The current reduces also the speed of the machine.
The serie REOHM 154 is available as braking resistor (series BW) or as charging resistor (series R).
As 154 R (Charging resistor, damping resistor, filter resistance, etc.)
The charging resistor is a current limiting resistor for the charging and discharging of capacitors and limitates for example the current flowing into the intermediate circuit capacitor inrush current. For this the device must be designed for a high single pulse energy and nominal voltage. The inductance of the resistor contributes to limit the inrush current, so wirewound resistors are the right choice.
