Soft Starter
ST100 Bypass Soft Initiator
A digital bypass soft starter using a microcontroller core and thyristor modules to bring squirrel-cage motors up smoothly under any load condition.
ST100 bypass intelligent soft starter employs sophisticated digital control technology, utilizing a microcontroller as its intelligent core and thyristor modules as the execution elements to achieve fully automated control of electric motors. Suitable for controlling squirrel-cage induction motors under various loads, ST100 bypass intelligent soft starter ensures smooth motor startups under any operating conditions, safeguarding the drive system, minimizing the impact of startup currents on the power grid, and guaranteeing reliable motor startup. Its smooth deceleration and soft stop feature effectively addresses the issue of shutdown surge in inertial systems, eliminating reverse-inertial impacts on the drive system, which is unachievable with traditional equipment. ST100 bypass intelligent soft starter has comprehensive system protection functions, which can extend system service life, reduce total system cost, improve system reliability, and is fully compatible with the functions of various starting devices. It is an ideal alternative to traditional star-delta and autotransformer starting methods. ST100 bypass intelligent soft starter

Problems it solves
Why this model gets specified
Squirrel-cage motors on varying loads start unevenly. Digital control with thyristor execution elements gives a smooth start under any operating condition.
Star-delta starting is cheap but crude, and shortens equipment life. ST100 is positioned as its direct replacement.
Motor damage from starting stress accumulates invisibly. Comprehensive protection features extend equipment service life.
Who it is for: Buyers replacing star-delta starters on squirrel-cage induction motors across mixed load types.
