Electric Motor Spare Parts 
>> Softer Starter

      J1 Series Soft Starter Is Used For Improving Motor Starting. It Overcomes Problems of Auto voltage reducing starter, Such as big Impulse current, Start difficulty, Heating, big Switch current. It is a ideal replacement of squirrel motor starter


  • Auto Digital Control¡£

  • 4 Starting methods: 1¡¢Current-Limited Starting; 2¡¢Voltage-Control Starting; 3¡¢Torque-Control Starting;4¡¢Torque plus Kick Control;

  • Starting Torque, Current, Voltage, Time etc. can be adjusted on optimum current impulse & torque control according different loads;

  • Starting Current can be adjusted according to load, reducing starting loss to reach optimum torque;

  • Gradual stopping can extend the service life of relay contact for meeting different mechanical application;

  • Protection of over-current, overload and default phase can safe equipment and electric motors;

  • Convenient outlet with multi-functions:  digital delay starting torque, gradual stopping input control, starting relay output, failure relay output;

  • Auto recognition & protection function of phase sequence;

  • Full digital set and output control function, it is convenient for users;

  • With standard RS232C inlet;

  • Two power supply separated to insure control part free of strong current interference.

QJR/Z-400/1140 Explosion-Proof Softer Starter
Function and Advantage£º
  1. Starting current can be set freely to reduce impulse to power supply;
  2. Starting time can be controlled freely: 0-80S adjustable;
  3. Belt acceleration even: 0.1-0.3 m/s adjustable, no mechanical shock;
  4. Self- diagnosis & protection function on Short current, over-voltage, over current, default phase;
  5. Long distance communication functions to make multi-machine working together and same power;
  6. Working current, torque of motor showed in real time, user can  know system working condition at a glance;
  7. All working diameter can be set on the spot (remote control, don't need to open explosion shield); very convenient.
