About This Product
Several Benefits in a Single Product
Combining convenience and innovation, the SSW900 is the right choice for complete motor protection and start/stop control. Developed for industrial or professional use, the new line of soft-starters allows easy and simple access to the configuration settings and data. Using a menu structure, the new interface of the SSW900 line presents an unprecedented experience of interactivity with the user, allowing adjustments and configurations with online parameter help right on the HMI, in addition to event logs with date and time and setup assistant. The equipment also has built-in bypass, which contributes to extending the useful life of the drive, optimizing space and reducing heat dissipation in electric panels.
The SSW900 soft-starters feature a microprocessor, are totally digital, incorporate state-of-the-art technology and are designed to ensure the best performance in the start and stop of induction motors, being a complete, low-cost solution. The operating interface also enables easy parameter setting, facilitating the start-up and operation. In addition, the built-in Pump Control function enables effective pump control, thus preventing water hammer, and the torque control function enables accelerations and decelerations with linear speed ramps.
