LDMS medium-voltage soft starter can reduce the voltage drop of the power grid caused by direct starting of the motor. The use of this product does not affect the normal operation of other equipment in the common network. It can reduce the impact current of the motor. The impact current will cause excessive local temperature rise of the motor and reduce the life of the motor; it can reduce the mechanical impact caused by direct starting, and the impact will accelerate the wear of the driven machinery; reduce electromagnetic interference. The impact current will interfere with the normal operation of electrical instruments in the form of electromagnetic waves. LDMS medium-voltage soft starter can start and stop freely and improve work effciency.
