ZFENG Soft starter precise current control, motor smoothly sets sail, bidding farewell to starting shock

A soft starter is a motor control device that integrates multiple functions, including soft starting, soft stopping, light-load energy saving, and various protection features for motors. It achieves a smooth start of the motor by gradually increasing its voltage and frequency, thereby reducing the current and mechanical shocks during startup. This extends the service life of the motor and related equipment. Soft starters are widely used in industrial automation, construction, energy, and other fields. They are suitable for various motor-driven equipment, such as water pumps, fans, compressors, and conveyor belts.

Current-limiting Starting: Limits the starting current to a preset value during motor startup, minimizing the impact on the grid voltage.

Voltage Ramp Starting: The output voltage increases linearly in a ramp-up manner, suitable for heavy-load starting.

Torque Control Starting: Controls the output voltage according to the linear increase in the motor's starting torque, providing a smooth and flexible start.

Combined Starting Modes: Such as torque plus sudden jump control starting, suitable for specific heavy-load starting scenarios.

Overcurrent Protection: Prevents motor damage due to excessive current.

Phase Loss Protection: Monitors the three-phase current of the motor to prevent operation with a missing phase.

Overheating Protection: Prevents motor damage due to overheating.

Leakage Detection: Ensures the safe operation of the motor and soft starter.

Equipped with an intuitive operation and display keyboard, allowing for modification and setting of parameters such as starting, stopping, running, and protection according to different loads.

Supports remote monitoring and control, enhancing the automation level of the system.

Adopts a modular design, featuring a small size for easy installation and use.

Combines an upper plastic shell and a lower metal structure to meet both aesthetic and robust requirements.

Reduces the starting current, minimizing the distribution capacity and avoiding additional investment in capacity expansion.
