Siemens Robicon Perfect Harmony Power Cells can be repaired. EMA has been repairing them for some time. The Robicon power cell repairs can vary from simply replacing the power devices (IGBT s) to completely rebuilding the power cell.
The Siemens Robicon Perfect Harmony medium voltage VFD has been a popular medium voltage VFD for many years. There is a significant installed base.
One of the most common failures is the power cells. The Perfect Harmony VFD has great diagnostics available from the keypad, and is great at identifying the actual Robicon power cell that has failed.
Here at EMA, we stock power cells which are available for immediate shipment in the event of an emergency. (see Robicon Power Cells in Stock HERE) .
We also repair and refurbish the Siemens Robicon Perfect Harmony power cells. We have done this as part of a preventive maintenance planned event, on emergency field service on Robicon medium voltage VFDs, and as a stand alone shop repair.
