Motor Soft Starters – PSE25-600-70

The PSE25-600-70 softstarter is an advanced device designed for smooth starting and stopping of three-phase motors. Using a softstarter reduces mechanical and electrical loads, extending the life of the motor and associated installation components. The device combines starting functions with built-in overload protection, providing comprehensive motor protection.

Design and Functionality

The PSE25-600-70 features a compact design and easy installation. It has a built-in bypass contactor, which minimizes energy losses after the starting process is complete. Control is via a two-phase system, and the device offers programmable current limiting and a "kick-start" function for demanding applications. A display with symbols provides intuitive operation and allows monitoring of operating parameters. Additionally, the PCBs are coated, increasing resistance to aggressive environments.

Applications and Benefits

This model of softstarter is ideal for a wide range of industrial applications, such as pumps, fans, compressors, conveyor belts and mixers. Thanks to the ability to regulate torque, the PSE25-600-70 is suitable for applications requiring precise start-up control. Using a softstarter translates to:

• Reduction of inrush currents: Limiting the inrush current reduces the load on the power supply network and minimizes the risk of overvoltage.
• Extended motor life: Smooth starting reduces mechanical stress on the motor and its accessories.
• Overload protection: Built-in overload protection protects the motor from damage in the event of an overload or short circuit.
• Configurability: Adjustment of start-up parameters allows optimization of device operation for specific application requirements.
• Ease of use: A clear display makes it easy to monitor the device status and configure parameters.

Technical Parameters and Compatibility

The PSE25-600-70 softstarter is designed to operate at a supply voltage of 208…600 V AC and a control voltage of 100…250 V AC (50/60 Hz). The maximum rated current is 25 A, allowing it to be used with motors up to 11 kW with a standard connection (400 V) or 7.5 kW with a star-delta connection (400 V). The device has a protection class of IP00, which means there is no protection against access to live parts and against the ingress of solids and liquids. The ambient operating temperature is up to 40°C. This softstarter also has a Modbus RTU interface for integration with industrial automation systems.
