PSTX170-600-70 90kw 75kw ABB Soft Starter Plc Programming Controller Module

1. Soft Starting for Medium-High Power Motors, Reducing Grid Inrush:Rated for 170 A, suitable for ~75–90 kW three-phase induction motors. Uses controlled voltage ramping to reduce inrush current (down to 3–5× rated current), minimizing stress on the power grid and mechanical systems.

2. Full-Digital Microprocessor Control with Adjustable Start/Stop Profiles:Features programmable start/stop curves (voltage ramp, current limit). Users can set start time, initial torque, and current limit based on load type (pumps, fans, compressors), ensuring optimal starting performance.

3. Comprehensive Motor Protection Integrated:Built-in protection against overload, stalling, phase loss, phase imbalance, overvoltage, undervoltage, thyristor overheating, and motor overheating (via PTC input). Real-time monitoring enhances system safety and reliability.

4. Integrated Bypass Contactor for High Efficiency:Equipped with vacuum or electromagnetic bypass contactor that automatically switches to direct-on-line (DOL) operation after startup. Eliminates thyristor losses, achieving >99% running efficiency, lower heat generation, and extended service life.

5. Graphical Local Display for Easy Commissioning:Features an LCD graphical display with intuitive menu (supports Chinese), showing real-time current, voltage, status, and fault logs. Enables local parameter setting, testing, and troubleshooting—no PC required.
