Dynamic Braking Resistors - Post Glover Resistors
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.
Dynamic braking (DB) resistors are designed according to the parameters of a given drive and/or application. Each drive has a specific minimum and maximum braking resistance chosen to the protect the drive itself.
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. The drive manufacturer normally determines the power rating (watts) needed to prevent overheating during braking duty.
Drive Size Calculated Resistor Power Size (Especially for small duty cycles, this calculated power size may not be final based on the short term energy during the braking event. This detail must be completed with the resistor manufacturer based on the chosen power size and resistor type.)

PLEASE NOTE: Post Glover dynamic braking resistors should be checked periodically for loose connections and the accumulation of dust and dirt. Service the unit if necessary. When doing so, remove all power and make sure the unit has cooled

How Dynamic Braking Resistors Work Dynamic Braking Resistors are used with AC Variable Frequency Drives to produce a braking torque in the motor during overhauling or braking conditions. The dynamic braking resistor is connected across the DC bus and will see voltages as high as 1000 volts.
Dynamic Braking Technology Resistors integrated into the power unit dissipate electrical energy created by electric braking systems. The dynamic braking resis-tor is connected to the DC bus and will see voltages as high as 800 volts during braking conditions. The drive manufacturer normally deter-mines the power rating (watts) needed to
