Description


As BW (Braking resistor)

When an electric machine operates as a generator (Electromotive brake), the brake resistor protects the machine from a voltage rise in the intermediate circuit. The current reduces als the speed of the machine. 

As 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.

Note

The ratings apply for 100 % duty cycle and free access and exit of cooling air.

In general: Is the ambient temperature higher than 40 °C, the continuous power must be reduced by 5 % per 10 K temperature rise.
