Smooth Start for High-Power Motors, Reducing Mechanical Stress:Rated for 1250 A, designed for large three-phase induction motors. Uses controlled voltage ramping to minimize mechanical shock and inrush current during startup, extending motor and driven equipment life.
Full-Digital Electronic Control with Precise Start/Stop Adjustment:Powered by a high-performance microprocessor, offering programmable start/stop profiles (voltage ramp, current limit). Users can customize start time, initial torque, and current limit based on load characteristics for optimal performance.
Comprehensive Motor Protection Built-In:Integrated protection against overload, stalling, phase loss, phase imbalance, overvoltage, undervoltage, overheating, and thyristor faults. Real-time monitoring ensures reliable operation and prevents equipment damage.
Integrated Bypass Contactor for High Efficiency:Features a built-in vacuum bypass contactor that automatically switches to direct-on-line (DOL) operation after startup. Eliminates power loss and heat generation from thyristors, achieving >99% running efficiency and lower operating temperature.
User-Friendly Interface for Easy Operation:Equipped with a graphical LCD display and intuitive menu (supports Chinese), showing real-time current, voltage, status, and fault logs. Enables local parameter setting, commissioning, and troubleshooting without external tools.
