Drive topology: The Siemens Perfect Harmony GH180 3500 HP VFD with 6900 Volts uses a cell-based topology, which makes it scalable and flexible. This means that the drive can be easily scaled up or down to meet the specific needs of the application. The cell-based topology also makes the drive more reliable, as it allows for the failure of individual cells without affecting the overall operation of the drive. This helps to ensure that the drive will be able to meet the needs of the application, even if there are changes in the future.
Proven IGBTs: The Siemens Perfect Harmony GH180 3500 HP VFD with 6900 Volts uses proven IGBTs, which are known for their reliability and efficiency. IGBTs are a type of semiconductor that is used to switch high voltages and currents. They are known for their high reliability and efficiency, and they are also relatively easy to manufacture. This helps to ensure that the drive will be able to operate reliably for many years.
Linked power cells: The Siemens Perfect Harmony GH180 3500 HP VFD with 6900 Volts uses linked power cells, which helps to improve availability and reliability. Linked power cells are connected in parallel so that if one cell fails, the other cells can continue to provide power to the drive. This helps to ensure that the drive will not experience a loss of power even if one or more cells fail. This helps to ensure that the drive will be able to operate reliably even if there are problems with the power supply.
Optimized synchronous transfer: The Siemens Perfect Harmony GH180 3500 HP VFD with 6900 Volts uses optimized synchronous transfer, which helps to reduce downtime during power outages. The optimized synchronous transfer is a feature that allows the drive to synchronize with the main power when it is restored after a power outage. This helps to minimize the downtime that is experienced during power outages. This helps to ensure that the drive will be able to resume operation quickly after a power outage.
