  1. Smart start. The intelligent motor soft starter comes with various startup modes, including limited current startup mode, voltage ramp startup mode, sudden start mode, current ramp startup and voltage current limiting double closed-loop startup.
  2. Multifunctional operation panel. LCD display for soft starter displays parameters intuitively, easy to operate.
  3. High continuity terminals. Reliable 3 phase soft starter features high-conductivity terminals made of quality and thickened material and good electrical conductivity is available.
  4. Powerful cooling. The motor soft starter provides effective heat dissipation protection so as to quickly reduce the operating temperature.
  5. Multiple protections in one machine. Smart motor soft starter is available with overcurrent, overload, overheat, low voltage, high voltage, load short circuit, output phase loss, input phase loss, three-phase unbalance protections.
  6. High and low temperature resistance. The electronic soft starter is made of industrial grade ABS plastics with high impact resistance, high heat resistance, stable and good performance.

  • Simple control panel. The control panel can be removed to clean, easy to operate, real-time data display on LCD screen.
  • Smart mainboard. Soft starter features fast response, multi-functions.
  • Power control transformer. It comes with energy saving, circulating circuit, high quality coils with insulation isolation.
  • Mutual inductor. the mutual inductor makes the soft starter more standard for measuring instruments, protection equipment and automatic control equipment.
