SINAMICS PERFECT HARMONY GH150

SINAMICS PERFECT HARMONY GH150

The next level of versatility for cell-based medium voltage drives

The SINAMICS PERFECT HARMONY GH150 features a series of low voltage cells that are linked together to create 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. The ability to bypass any cell during operation in less than 5 ms, and maintain the full output voltage, is why it offers your application maximum availability. The drive offers some unique features that contribute to its versatility like a separate transformer and control cabinet configurations, marine certification, and Arc Fault tested design.

Benefits at a glance

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.

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.

Available in marine/offshore configurations that meet the requirements of all major marine certification societies.

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.

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.

Internal arc certification based on IEC 62271-200. Eases plant safety concepts by providing safer drive operation.

This option enables you to quickly stop your process or application for safety or production purposes.
