PowerFlex 755TM Control Pod Rule
Every PowerFlex 755TM common bus inverter in the common bus system needs one control pod. This can be achieved by combinations of C11 -
single pod (with control bay) and or C12 - dual pod (with control bay) control options.
DC Bus Conditioners
The DC bus conditioner is used to reduce voltage stress levels on components such as optos, circuit boards, and magnetics. A reduced voltage level
increases the reliability of components.
Bus conditioner modules are used with frame 8…15 PowerFlex 755TM regenerative bus supplies, PowerFlex 755TL/TR drives, and PowerFlex 755TM
non-regenerative supplies, single density (1X), and dual density (2X) modules. Frame 6…7 PowerFlex 755TM regenerative bus supplies and frame
5…7 PowerFlex 755TL/TR AC drives have built-in bus conditioner circuits.
Bus conditioner modules are factory installed and available as options (-P50 and -P51). You should only specify the -P50 or -P51 optional factory
installed bus conditioner if your power system isn’t solid grounded.
