General description

The SINAMICS PERFECT HARMONY GH150, like its cell-based counterpart SINAMICS PERFECT HARMONY GH180, features a series of low voltage cells that are linked together to build the medium voltage power output of the drive system. With this cell-based design, the drive can be scaled precisely for a very wide range of voltage and output power.

Due to its modular design and ability to bypass any cell during operation and still maintain the full output voltage, the SINAMICS PERFECT HARMONY drives offers maximum availability to an application.

SINAMICS PERFECT HARMONY GH150 drives are specially designed to offer expanded versatility and easy integration. The SINAMICS PERFECT HARMONY GH150 offers some unique features like a separate transformer design, a separate control cabinet, marine certification and an arc fault tested design.

Особенности


  • Transformer Versatility: Able to utilize separate dry-type or oil-filled standard converter transformers. It is also capable of accepting transformers of different primary voltages or number of pulses.
  • Greater Control Cabinet Flexibility: Flexible control cabinet placement enables optimization of plant layout and safety concepts with ability to install control cabinet in an alternative location or orientation to the drive.
  • Marine and Offshore Certification: Available in marine/offshore configurations that meet the requirements of all major marine certification societies.
  • Cell Bypass and Cell Redundancy: Maximize your process availability thanks to cell bypass and redundant cells. High-speed cell bypass feature maintains a reliable and balanced output voltage without torque or speed reduction.
  • Extremely Motor Friendly: Capable of being configured with virtually any motor thanks to an almost sinusoidal output voltage. The motor friendliness of the drive is perfect for retrofits and long motor cable applications.
  • Arc Fault Tested: Internal arc certification based on IEC 62271-200. Eases plant safety concepts by providing safer drive operation.
  • Braking Chopper: This option enables to quickly stop the process or application for safety or production purposes.
