Advanced Motor Starting with PSTX30-600-70

Softstarter PSTX30-600-70 is an advanced device used for smooth motor starting and control of three-phase motors, designed for demanding industrial applications. It offers comprehensive motor and load protection, as well as a range of functions to increase efficiency and reliability. The device is particularly useful in applications where limiting mechanical shocks during start-up is important, such as pumps, fans, compressors, or conveyors.

Functionality and Application

PSTX30-600-70 features a built-in bypass, which ensures minimal energy loss during motor operation. It has adjustable torque control, allowing precise adjustment of start-up parameters to the specifics of the load. Built-in overload protection protects the motor from damage caused by excessive load. Equipped with a graphic display, it facilitates configuration and monitoring of operating parameters. Additionally, the built-in Modbus RTU interface enables integration with automation systems and remote control.

• Wide voltage range: Operation in the range of 208…600 V AC makes the device universal and can be used in various electrical installations.
• Motor protection: Built-in overload protection and short-circuit detection ensure long-term and safe motor operation.
• Torque control: Torque control allows for optimization of the start-up process and minimization of mechanical shocks.
• Modbus RTU communication: Enables integration with SCADA and industrial automation systems.
• Durable construction: Printed circuit boards coated with a special coating provide resistance to aggressive chemical environments.
• Removable control panel: Facilitates servicing and replacement of the device without interrupting the installation operation.

Operating parameters and construction

Softstarter PSTX30-600-70 is designed to operate in ambient temperatures up to 40°C. The IP00 protection class indicates that the device is intended for mounting inside electrical cabinets. The device is adapted to cooperate with both motors connected in star (internal delta), and motors connected directly (standard connection). Automatic detection of the connection configuration simplifies installation and configuration. The rated current of the device is 30A at an ambient temperature of 40°C, and the rated power for three-phase motors is 15 kW at 400 V and 25 kW with an internal delta connection at 400V, respectively. A built-in relay indicates the operating status of the device (RUN, TOR) and any failures (Event).
