Perfect Fit for Small Industrial Motors:Rated at 37 A, suitable for 15–18.5 kW three-phase induction motors. Ideal for small pumps, fans, and compressors, reducing mechanical and electrical stress during startup.
Full-Digital 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 & System Protection: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:Equipped with 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 Local Display for Easy Commissioning & Maintenance:Features an LCD graphical display with intuitive menu (supports Chinese), showing real-time current, voltage, run hours, and fault logs. Enables local setup, testing, and troubleshooting—no PC required.
