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.
