3. Product Features & Advantages
3.1 Core Technical Superiority
Patented TCS Torque Control Technology: The ATS48C48Y adopts Schneider Electric’s exclusive Torque Control System (TCS) gradient control technology, replacing traditional voltage ramp starting methods. This innovative technology enables smoother, more precise motor starting control, eliminating mechanical jitters and current spikes that are common with conventional soft starters.
Bidirectional Torque Limitation: Beyond standard starting current limitation, this unit supports current limitation during motor stopping, making it perfectly suited for heavy-duty applications and frequent start-stop operating conditions that demand enhanced control stability.
High-Precision Current Limitation: The starting current can be accurately limited to approximately 2.5–3 times the rated current, drastically reducing impact on the power grid and motor components, while preventing grid voltage fluctuations and equipment wear.
