The ST200 online soft starter

The main functions of soft starters:

● Effectively reduce the starting current of the motor; decrease distribution capacity and avoid investment in capacity expansion in the power grid.

● Reduce the starting stress of the motor and load equipment; extend the service life of the motor and related equipment.

● Soft stopping function effectively solves the parking vibration problem of inertia system, which cannot be achieved by traditional starting equipment.

● Six unique starting modes to adapt to complex motor and load situations for perfect starting performance.

● Perfect and reliable protection features effectively ensure the safety of the motor and related production equipment.

● Application of intelligent and networked technology in the motor control technology of the soft starter meets the higher requirements of the rapidly developing power automation technology.

Main features of soft starters:

● Reliable quality assurance:

    - Computer simulation design;

    - SMT chip production technology;

    - Excellent electromagnetic compatibility performance;

    - High-temperature aging and vibration testing before delivery.

● Perfect and reliable system protection features:

    - Under-voltage, over-voltage and loss of voltage protection;

    - Overheating and prolonged starting time protection of soft starters;

    - Input phase loss, output phase loss, and three-phase unbalance protection;

    - Overcurrent, overload, and short-circuit protection during operation.

● Maintenance functions:

    - Self-diagnosis of faults (short-circuit, overvoltage, undervoltage, single-phase grounding, motor overload, phase loss, blockage, and intelligent programming to judge the work status of the dragging system);

    - Modular combination design; quick troubleshooting based on displayed fault content.

● Products with independent intellectual property rights:

    - Independent software copyrights;

    - Proprietary motor starting and protection technology;

    - Unique testing and debugging equipment and process.

● Fast and thoughtful after-sales service:

    - Reliable performance and quality lay a solid foundation for high-quality service;

    - Provide excellent and comprehensive matching design solutions;

    - Timely and thoughtful consultation;

    - Continuously improve product performance based on customer feedback.
