Effectively protect motors while saving energy

A comprehensive solution for soft starting and stopping of three-phase asynchronous motors that increases uptime and reduces maintenance requirements.

By integrating soft starters with AC motors, you can save energy, space and costs and increase the lifetime of your system by reducing wear on motors, power cables and the electrical distribution system. And there is no need to consider filters and screened cables, as soft starters generate zero harmonics.

Supply voltages and power range

  • 3 x 200-690 V...7.5-850/2400* kW (1600 A)

*Inside delta connection

  • 24 V DC or 110-240 V AC

Features and benefits

Easy connectivity for the soft starter to EtherNet/IP-based networks, such as Rockwell PLC systems

Programming is quick and easy thanks to three menu systems (Quick Menu, Application Setup and Main Menu), a four-line graphical display and a logic keypad

The best starting and stopping profile for the application is chosen using Adaptive Acceleration Control

Motors can be used to their full potential without risk of damage from overloading due to second-order thermal model

Installation costs are lower and there is less stress on the motor thanks to DC injection braking distributed evenly over three phases

Space can be saved, cabling costs reduced and retrofitting made easier as a result of adjustable bus bars which allow for both top and bottom entry

    Variable speed control of a chiller allows you to provide constant pressure regulation while matching the capacity to the actual need based on measurements in the system. Speed control is beneficial when a compressor runs for long periods at partial load. Reduce operational costs by running applications at a lower speed which reduces energy consumption. And reduce installation costs by optimizing the system and the compressor itself.
