The basic difference between soft starters and VFDs is that the VFD is used to achieve control over the motor speed whereas the soft starter is used for reducing the inrush current. Variable frequency drives and soft starters are energy-efficient devices....
Both VFDs and soft starters replace conventional contactor relays as well as the overloads since they both contain internal overload protection. In turn, this also protects the AC electric motor from damage. SPEAK WITH AN EXPERT What Are the Applications for VFDs and RVSSs? Use VFDs in ...
