The single-axis Sinamics S120 AC drive features a modular concept that separates power and intelligence. Freely selectable combinations of power sections and controllers increase flexibility and scalability of the drive system. Multiple choices allow users to select the right controller for their current needs but protect their drive investments if the application ever changes. The Sinamics S120 AC Drives are available in single phase 230V in the power range of 0.25-1hp, and three phase 460V in the power range of 0.5-400hp. The power modules are available in compact block construction (0.25-125hp) or as chassis units (150-400hp).Siemens Energy & Automation Inc.www.sea.siemens.com800.964.4114
