CTWV Series High-Voltage Solid-State Soft Start Device

The CTWV Series High-Voltage Solid-State Soft Start Device is an advanced motor starting solution designed for high-voltage AC motor applications. It adopts advanced MCU control technology, SCR phase control, optical fiber communication, and intelligent protection functions to provide smooth motor starting and reliable operation.

The CTWV high-voltage soft starter precisely controls the thyristor conduction angle to achieve stepless voltage rising during motor starting, reducing starting current, mechanical impact, and electrical stress. After the motor reaches stable operation, the bypass vacuum contactor closes to allow direct grid operation, improving efficiency and extending equipment service life.
