The most proven MV drive on the market today with a cell-based design perfect for meeting high efficiency and availability application requirements.

The SINAMICS PERFECT HARMONY GH180 is a series of low voltage cells linked together to create the medium voltage power output of the drive system. The design features an integrated transformer and the ability to scale the drive for a wide range of voltage and output power. The drive offers increased availability due to its modular design and ability to bypass any one cell during operation. The quality of the output voltage is so close to perfect sine-wave shape that motors of literally any type – old or new, low-speed or high-speed – can be operated without any additional stress.

  • Extremely motor friendly as a result of an almost sinusoidal output wave form
  • Higher reliability due to the drives’ cell bypass capabilities which keeps the drive and your application running even in the event of a cell failure.
  • Higher availability due to the drives’ cell redundancy and cell bypass features.
  • Maintenance and process friendly due to faulted cells being replaceable at your next available maintenance period.
  • Very small footprint with an integrated air or water cooled transformer.
  • Able to support long cable applications in excess of several kilometres.
