Softstarter Uwe=3x400V AC, Iwy=22A, Pmax=11kW SF-110

Intelligent motor starting control – Softstart SF-110

This advanced device is designed for smooth and safe starting of three-phase asynchronous motors. Softstart SF-110 is an alternative to traditional star-delta starting systems, eliminating high inrush currents when starting loaded drives, such as mills or crushers. Using this type of solution translates into reducing the load on the electrical network and extending the life of the motor.

Versatile application and functionality

Softstart SF-110 offers full control over the starting process, allowing adjustment of torque, current and power both during the starting phase and during motor operation. Built-in protections protect the motor against overload, underload and voltage fluctuations. The device has a control panel with a keyboard and LED display, making configuration and monitoring of operating parameters easier. Additionally, an analog output for current control and programmable relay outputs increase system flexibility.

Key features and benefits:

• Smooth start: Eliminates inrush currents, reducing the load on the power supply network and extending the motor life.
• Versatile protection: Protection against overload, underload, overvoltage and undervoltage ensures reliable system operation.
• Precise control: Adjustment of torque, current and power allows for optimization of the starting process for different types of motors and applications.
• Intuitive operation: Control panel with LED display makes configuration and monitoring of operating parameters easier.
• Wide integration possibilities: Programmable relay outputs and analog output enable integration with automation systems.
• Fault memory: Facilitates diagnostics and troubleshooting.
• Automatic restart: Automatic motor restart function increases system reliability.
