SF-150 soft start
Three-phase soft starter.
Input voltage 3 x 400 V
Maximum power 15 kW
The SF soft starters are used to perform a safe boot of three-phase asynchronous squirrel-cage motors. Soft starter eliminates a star-delta systems and drastically reduces the current surge that occurs during start-up of even heavily loaded motors (e.g. mills and grinding machines).
Functioning
Motor starts on all three phases of the power supply, which prevents the asymmetry of grid load and the uneven load of the motor windings. In addition, the soft starter is equipped with advanced security features to protect the motor during start-up, operation and braking.
