PSTX105-600-70 55kw 45kw ABB Soft Starter Plc Programming Controller Module

Ideal for Medium-Sized Motors with Smooth & Reliable Start:Rated at 105 A, suitable for 45–55 kW three-phase induction motors. Widely used for soft starting fans, pumps, compressors, reducing mechanical stress and protecting motor and driven equipment.

Full-Digital Microprocessor Control with Adjustable Start Profiles:Features programmable voltage ramp, current limiting, and soft stop functions. Users can set start time, initial torque, and current limit to match specific load requirements for optimal performance.

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

Integrated Bypass Contactor for >99% Running Efficiency:Equipped with an integrated vacuum or electromagnetic bypass contactor that automatically switches to direct-on-line (DOL) operation after startup. Eliminates thyristor losses, reduces heat, and improves energy efficiency.

Graphical LCD Display for Easy Operation & Commissioning:Features an LCD graphical local control panel with intuitive menu (supports Chinese), showing real-time current, voltage, run hours, and fault logs. Enables local setup, testing, and troubleshooting—no PC required.
