LOW AND MEDIUM VOLTAGE AC DRIVE SYSTEMS

From the smallest AC drive to AC drives in the horse power ranges needed for ships propulsion, Legacy can provide the system to suit your needs. With our committed relationship with the Siemens Drive Group, Legacy can provide a manually operated system or a fully integrated automated system to meet the needs of your power and process control requirements.

Marine propulsion applications all include an integrated power limiting system which communicates directly with power generation controls to prevent blackout occurrences during large power demands and limited power generation units attached to the common main bus. The Legacy PnP Power Generation Control System is designed to interface directly with all drives so if you’re entire system is designed by Legacy, this problem eliminated.

Often the toughest question when deciding on a specific AC drive package is whether you actually need an AC Drive or not. Then after you decide that an AC drive does fill the applications need, there is the selection of the type of drive to provide. Legacy has provided specific details in the form of PDF files located in the Document section of this web site. Information has been included which will give you information to help make your choice.

Choices such as Active Transistor Front Ends, SCR current regulated front ends, passive front ends or no front end are just a very few of the choices when selecting an AC drive for your application. The most important aspect of long term, trouble free system performance is that the proper drive system is provided the first time around.
