Softstart PSE105-600-70 1SFA897109R7000

Soft Starters – Smooth Start and Motor Protection

This soft starter, model PSE105-600-70, is an advanced device designed for controlled starting and stopping of three-phase motors. It not only provides a gentle start, reducing mechanical and electrical loads, but also offers built-in protection, protecting the motor from overloads. The device is particularly useful in applications requiring limitation of starting currents and precise control of torque.

Functionality and Application

The PSE105-600-70 soft starter finds application in a wide range of industrial applications, such as pumps, fans, conveyors and compressors. Thanks to the ability to adjust the torque, it is ideal for situations where control of the starting process is required, e.g. to avoid hydraulic shocks in pumping systems. The built-in bypass contactor minimizes energy losses during motor operation in a steady state. It is equipped with a clear display to facilitate configuration and monitoring of operating parameters.

Key Features and Benefits

• Wide voltage range: The ability to operate in networks with a voltage of 208 to 600 V AC provides installation flexibility in various conditions.
• Built-in protection: Motor overload protection protects against damage caused by excessive load.
• Torque adjustment: Allows you to adapt the starting characteristics to the specific requirements of the application.
• Built-in bypass contactor: Reduces energy losses and simplifies electrical connections.
• Clear display: Facilitates configuration and monitoring of device parameters.
• Compact dimensions: Allows mounting in limited space.
• Wide range of rated currents: Supports motors with a current of up to 105A (at 400V - power 55kW).
• Universal control voltage: Possibility of powering control with both 100-240V AC and 24V DC (depending on the version).
• Resistance to environmental conditions: Coated PCBs ensure reliable operation even in aggressive industrial environments.

Additionally, this soft starter offers programmable current limitation and a "kick-start" function, which increases its versatility and allows for optimization of the starting process for different types of loads. This allows installers to easily adapt the device to the specific needs of the customer, and end users to enjoy reliable and efficient motor operation.
