18-pulse drive MCCs

Siemens tiastar motor control centers with integrated 18-pulse ac drives technology offer a simple, clean power motor control solution. With a modular, open-architecture design, tiastar MCCs are rugged, time-proven, and have many features and options to meet the needs of water/wastewater applications. Engineered with integrated components to reduced line harmonics, tiastar MCCs do more than simply meet IEEE 519 requirements, they offer high-level operating efficiency while reducing energy consumption and downtime.

  • Increase service life of process equipment with active management of assets including motors and pumps 
  • Improve power quality and operating efficiency result in energy savings
  • Process control flexibility to increase overall operational performance.
