SINAMCIS PERFECT HARMONY variable frequency drive product line features 50+ proven technologies designed to provide a reliable solution for critical applications. The medium-voltage power output of the VFD drive system is created by linking a series of low-voltage power cells, offering a scalable solution for a wide range of voltage and output power from 2.4 - 7.2 kV.
This modular design also facilitates the drive’s most innovative feature, Advanced Cell Bypass, which allows the drive to maintain consistent output if one or more cells fail. In the event of a fault, the drive isolates the output of the failed cell and reconfigures the power section to bypass the cell without interrupting performance — all in less than a quarter of a second. The quality of the voltage waveform remains virtually unchanged even when only a single cell per phase remains operational.
With more than 10,000 drives sold worldwide, SINAMICS PERFECT HARMONY variable speed drive has helped industries across the globe achieve greater reliability for their critical processes, even in the harshest operating environments.
In the sections below, you can read case studies about the industry-specific applications we’ve helped optimize, our white paper that compares TCO across various VFDs and our white paper that shows how VFDs can reduce your operating and maintenance costs.
