Product Description


Product Description


KSSHV voltage soft starting can reduce the power grid voltage drop caused by the direct start of the motor. The use of this product does not affect the normal operation of other equipment in the common network, and can reduce the impulse current of the motor, which will cause the local temperature rise of the motor to be too large and reduce the life of the motor. It can reduce the mechanical impact caused by direct starting and accelerate the wear of the transmission machinery. Reduce electromagnetic interference, the impact current will interfere with the normal operation of the electrical instrument in the form of electromag-neticwaves, high voltage soft start can start and stop freely, improve work efficiency.
High voltage soft start devices include KSSHV-6 standard 6kV solid state soft start device, KSSHV 0 standard 10kV solid state soft start device and KSSHV-E series all-in-one high voltage solid state soft start device.
KSSHV high voltage soft start is suitable for starting AC motors with rated voltage 6-10KV. Products are
widely used in large-scale iron and steel, petroleum, chemical, aluminum, fire, mining, sewage treatment,
electric power and other industrial fields, can be well used with motor drive equipment. Such as: pumps,
fans, compressors, shredders, mixers, belt machines and other mechanical and electrical equipment.
