Siemens Robicon SINAMICS PERFECT HARMONY GH180
The most mature MV drive on the market today, with a unit-based design, is very suitable for meeting the needs of high efficiency and availability applications.
SINAMICS PERFECT HARMONY GH180 is a series of units connected together to create the medium voltage power output of the drive system. The design has an integrated transformer and can proportionally adjust the driver's voltage and output power range. The drive provides higher availability due to its modular design and the ability to bypass any unit during operation. The quality of the output voltage is so close to a perfect sine wave shape that almost any type of motor (old or new, low speed or high speed) can be operated without any additional stress.
