Medium and high voltage Ac motorsolid-state soft starter cabinets
Designed with multiple control functions to accommodate different load conditions, the SHMV-DN enables smooth motor acceleration while requiring minimal starting current. This effectively reduces power grid voltage drops during startup and significantly decreases both electrical current surges and mechanical stresses.
When soft stopping functionality is required, the system delivers a controlled, gradually decreasing voltage to the motor, ensuring smooth deceleration of the entire drive system. The SHMV-DN series combines intelligent control capabilities with reduced starting current impact, making it particularly suitable for industrial applications involving medium and high voltage motor operations.
