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 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.

Benefits at a glance

Upgrade your drive without giving up critical space.
SINAMICS PERFECT HARMONY GH180 fits easily into retrofits and other applications where space is at a premium.

A simplified system with enhanced serviceability and reduced commissioning – in some instances commissioning time is as little as 1–2 days!

Benefit from tremendous savings are realized on cables and conduit, installation and lifetime operating costs.
