Ideal for Small Industrial Motors with Smooth Start:Rated at 45 A, suitable for 18–22 kW three-phase induction motors. Widely used in small pumps, fans, and compressors to reduce inrush current (down to 3–5× rated current), protecting both power grid and mechanical systems.
Full-Digital Microprocessor Control with Adjustable Start Profiles:Supports programmable voltage ramp, current limiting, and soft stop modes. Users can set start time, initial torque, and current limit to match specific load types, ensuring optimal starting performance.
Comprehensive Motor Protection for Enhanced Safety:Built-in protection against overload, stalling, phase loss, phase imbalance, overvoltage, undervoltage, thyristor overheating, and motor overheating (via PTC input). Real-time monitoring prevents damage and improves system reliability.
Integrated Bypass Contactor for High Efficiency:Features an integrated vacuum or electromagnetic bypass contactor that automatically switches to direct-on-line (DOL) operation after startup. Eliminates thyristor losses, achieving >99% running efficiency and lower operating temperature.
Graphical LCD Display for Easy Operation & Commissioning:Equipped with 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.
