Multiple starting modes
Current-limiting start, ramp current-limiting start and voltage ramp start can meet the site requirST100ents to the maximum extent and realize the best starting effect.
High reliability
High performance microprocessor conducts digital processing for signals in control systST100, avoiding the excessive adjustment to analog line so as to obtain the best precision and execution speed.
Powerful anti-interference performance
All external control signals adopt optoelectronic isolation and are set with different anti-noise levels. The device is applicable for use in special industrial environment.
Optimized structure
The unique compact structure is designed to be easily integrated into user’s existing systST100, saving expenses for restructuring of systST100.
Motor protection
Multiple motor protection functions such as over-current, input/output phase-failure, short circuit of thyristor and overheat protection can guarantee motor soft starter not to be damaged in case of fault or incorrect operation.
Easy maintenance
Pilot signal coding systST100 composed of 4-digit number display monitors working condition
