SINAMICS PERFECT HARMONY GH180

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

sinamics gh180

The SINAMICS PERFECT HARMONY GH180 is a series of 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.


Your Benefits

  • 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 kilometers.

Features

  • No output transformer required – motor voltage 2.3 to 11 kV can be provided directly.

  • No harmonic line filters or power factor compensation required.

  • The cell bypass option ensures automatic bypass of a failed power cell in typically 250 milliseconds or less (less than 1/2 of a second).

  • The ProToPS option provides a hierarchical system of warnings instead of tripping the drive and automatically shutting down the system due to a malfunction. This control strategy allows time to evaluate the situation and respond appropriately to avoid a system shutdown.

  • No common mode motor insulation stress – the drive includes an integral isolation transformer.

  • Compatible with both new and existing induction or synchronous motors from any manufacturer without any special design considerations.

  • No significant drive-induced torque pulsations – even at low speeds.

  • The drive is able to ride through voltage dips or power outages.

  • For fiber industries – the drive can provide high output voltage at low power.
