2. Key Selling PointsIdeal for Small-to-Medium Motors with Smooth & Reliable Start:Rated at 72 A, suitable for 30–37 kW three-phase induction motors. Widely used for soft starting pumps,
fans, and compressors, reducing mechanical stress and protecting
motor and driven equipment. 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 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 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.
