1756-EWEB Soft starter is a motor control device that integrates soft start, soft stop, light load and energy saving and a variety of protection functions. By using voltage reduction technology, it reduces the voltage during the motor startup and gradually increases the voltage during the startup process, thus achieving a shock-free and smooth start of the motor throughout the startup process.

The main component used to regulate voltage in a soft starter is a semiconductor switch such as a thyristor (SCR). Adjusting the trigger Angle of the thyristor can adjust the voltage provided through it. Other components such as OLR (Overload relay) are used for overcurrent protection.

1756-EWEB Soft starter is a motor control device that integrates soft start, soft stop, light load and energy saving and a variety of protection functions. Its starting modes include ramp boost soft starting, ramp constant current soft starting, step jump starting, pulse impact starting, etc., which can be adjusted according to needs. The core component of the soft starter is the anti-parallel thyristor, which controls the output voltage by controlling the opening Angle of the thyristor, so as to realize the soft start and soft stop of the motor.

The advantages of the 1756-EWEB soft starter include reducing the impact on the power grid when the motor is started, reducing the failure rate of the motor, extending the service life of the motor, and also helping to achieve automatic control and improve production efficiency. In addition, the soft starter also has an energy-saving function, which can automatically adjust the output voltage and current according to the load situation, so as to achieve the purpose of energy saving.

In short, the soft starter is a powerful and widely used motor control device, which can realize the smooth start and stop of the motor, improve the stability and reliability of the motor, and also provide strong support for automatic control and energy saving and emission reduction.
