In a move that would give it the broadest selection of large-scale power-quality products in the industry, S&C Electric Co. announced it has purchased the large-scale power-quality business products unit from Siemens Power Transmission and Distribution, Raleigh, N.C. Terms of the transaction were not disclosed.

The operation, located in Orlando, Fla., designs and manufactures dynamic voltage restorers and other power quality and stability devices for high-tech customers. The Power Quality business operation will be integrated into S&C's Power Electronics Division, which is responsible for the PureWave family of power-electronic switching systems.

The products, which will be sold direct to end-users, will be marketed under the PureWave DVR and PureWave DSTATCOM brand names.

Chicago-based S&C Electric will move production of the Power Quality business operation to S&C's Power Electronics Division in East Troy, Wis. The former Siemens engineers from that unit, now S&C employees, will remain in the Orlando area. S&C said it plans to retain all the former Siemens employees associated with the product line.
