Advanced motor starter – Softstart PSTX105-600-70

Softstart PSTX105-600-70 is an advanced device used for controlled starting of three-phase motors. It provides smooth start and stop, reducing mechanical and electrical loads on the installation. The device is characterized by high reliability and durability, thanks to the use of coated printed circuit boards resistant to aggressive chemical environments. It is an ideal solution for both demanding industrial applications and standard installations.

Functionality and construction

PSTX105-600-70 offers comprehensive motor protection, including a built-in overload protection. It has a built-in bypass contactor, which minimizes energy losses after the start-up is completed. Adjustable starting torque allows you to adapt the start-up parameters to the specifics of the load. Additionally, the device is equipped with a removable control panel with a graphic display, making configuration and work monitoring easier. Communication is via a built-in Modbus RTU interface.

Key advantages and applications

• Versatility: Designed for motors with a voltage of 208…600 V AC and a power of up to 55 kW (at 400 V).
• Motor protection: Built-in overload protection ensures safe operation of the device and protects the motor from damage.
• Load reduction: Smooth start-up reduces current and mechanical shocks, extending the life of the motor and installation.
• Ease of use: Removable control panel with display simplifies configuration and diagnostics.
• Communication: Built-in Modbus RTU interface enables integration with automation systems.
• Resistance to external conditions: Coated printed circuit boards ensure reliable operation even in harsh environmental conditions.
• Automatic connection detection: Automatically recognizes star or delta connection, eliminating the need for manual configuration.

The device finds application in a wide range of applications, such as pumps, fans, compressors, conveyors and other devices using electric motors. It is particularly recommended where motor protection, load reduction and smooth start and stop are required. Thanks to the possibility of adjusting the starting torque, the start-up process can be optimized for different types of loads.
