Ideal for High-Power Motors with Smooth Start:Rated at 720 A, suitable for 320–400 kW three-phase induction motors. Widely used in large pumps, fans, compressors, and conveyors to reduce inrush current (down to 2.5–5× rated current), protecting both power grid and mechanical systems.
Full-Digital Microprocessor Control with Adjustable Start Profiles:Supports programmable voltage ramp, current limiting, kick-start + current limit, and soft stop modes. Users can set start time, initial torque, kick voltage, and max current limit to match high-inertia or heavy-duty loads.
Comprehensive Motor & System Protection:Built-in protection against overload, stalling, phase loss, phase imbalance, overvoltage, undervoltage, thyristor overheating, motor overheating (via PTC), start timeout, and repeated start protection. Real-time monitoring prevents damage and improves system reliability.
Integrated Bypass Contactor for >99% Running Efficiency:Features an integrated high-current 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:Equipped with an LCD graphical display with intuitive menu (supports Chinese), showing real-time three-phase current, voltage, run hours, and fault logs. Enables local setup, testing, and troubleshooting—no PC required.
