For example: an 1Kw resistor can take 2-5Kw peak power if braking time is short than 2 seconds. do/eQtK Braking Resistor Dynamic braking resistorsare used on AC variable frequency drives (VFD's) to dissipate energy that is produced in the motor as the drive providesbrakingtorque to stop the motor. In this kind of braking, the dc shunt motor is detached from the power supply & a braking resistor (Rb) is connected across the armature. Owner's manual says to clean the dynamic braking resistor. 5% OHL 50% Braking 25% OHL 50% OHL 100% OHL PowerFlex 40 Input The braking resistor must be installed as a free-standing unit.
