Dynamic Braking Resistors
The drive manufacturer normally determines the power rating (watts) needed to prevent overheating during braking duty.
The peak braking current is determined by the specified resistance value.
Each drive manufacturer specifies a resistance range with a minimum to prevent overcurrent and damage to the drive and a maximum value to give adequate lower dissipation capability.
Dynamic Braking Resistors that can be delivered quickly, completely assembled, and ready for convenient installation. Dynamic Braking Resistors are used with AC VFD’s to produce a braking torque in the motor during overhauling conditions. The dynamic braking resistor is connected across the DC bus and will see voltages as high as 800 volts.
