Function

Soft start and soft stop

Smooth start-up is achieved through an adjustable voltage ramp, reducing the current impact during start-up (up to three times the rated current), and protecting the motor and the power grid.

It provides a soft stop function to gradually reduce the voltage and avoid the "water hammer effect" in the water pump system.

Two-phase control technology

Two-phase control is adopted to minimize the three-phase current during the start-up process, eliminate the DC component and reduce electromagnetic interference.

Avoid the current and torque peaks generated by traditional star-delta starters.

Built-in protection function:

Overload protection: Built-in electronic overload protection to prevent the motor from overheating.

Phase failure protection: Detect power phase failure to prevent motor damage.

Over-temperature protection: Monitor the temperature of the soft starter to prevent overheating faults.

Self-diagnostic function: Detect internal faults and provide status feedback.

Parameter adjustment

Supports parameter adjustment such as startup time and current-limiting value to adapt to different load characteristics.

The front knob adjustment is simple to operate and no complex programming is required.

Energy conservation and status indication:

It has energy-saving functions when under light load, reducing energy consumption.

Equipped with LED indicator lights (green: operation, red: fault), it is convenient for status monitoring.

Bypass function: After the motor reaches its normal speed, the internal bypass contactor is connected, reducing power loss during operation and improving efficiency.

Application scenarios

Industrial Automation

It is used to control three-phase asynchronous motors, such as pumps, fans, compressors, conveyor belts, etc., to reduce starting shock and extend the service life of the equipment.

It is applicable to manufacturing production lines, packaging equipment and material handling systems.

Water treatment and pumping stations: The soft stop function effectively avoids the "water hammer effect" in the pump system, making it suitable for sewage treatment, water supply systems, and irrigation equipment.

HVAC system: Controls ventilation equipment, air conditioning compressors, etc., ensuring smooth start-up and reducing the impact on the power grid. It is suitable for commercial buildings and industrial facilities.

Food and beverage industry: Used in food processing equipment (such as mixers, conveyors), providing smooth start-up and reliable protection, meeting strict hygiene and safety requirements.

Traditional system upgrade: Replace the traditional star-delta starter or directly start the equipment to enhance system efficiency and reduce maintenance costs. It is suitable for the renovation of old factories.

Explosion-proof environment: Compliant with the ATEX directive, it is suitable for increased safety type (EEx e) explosion-proof motors and is widely used in hazardous environments such as petroleum and chemical industries.
