What is Soft Starter? Its Working, Diagram and Applications
The soft starter is a type of motor starter that uses the voltage reduction technique to reduce the voltage during the starting of the motor. The soft starter offers a gradual increase in the voltage during the motor startup.
This book is written with the thought of being a general guide for people working with softstarter applications but also for those just interested in learning more about this type of starting method.

This guide will help you set the basic settings on PSTX softstarter. Motor heating. We can use the Motor heating as a pre-start function to heat the motor before starting. Or use it as an individual function operated from digital input or with Fieldbus in combination with PTC or PT100 sensor. Pump application.
Soft Starter (Inrush Current Limiter) for AC and DC Loads
Step 1: Inrush Current Spike Captured on the SDS1104X-E DSO (Single-Shot Mode) AC Soft Starter. Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage.
Soft start enhances motor start performance in many ways including: Smooth acceleration without the torque transients associated with electro-mechanical reduced voltage starters.
the printed circuit board. A common volt-age is 100 - 250 V AC. Control circuit voltage (Uc), is the voltage for controlling the start and stop command of the softstarter. Common values are 24 V DC or 110 - 240 V AC. On many softstarters, the control voltage can be supplied internally.

The soft starter protect the motor from overcurrent and torque that occurs during starting of the motors by regulating the voltage applied to the motor.
