    High Start Torque Thyristor Electronic Soft Starter For Asynchronous Electric Motor

    High start torque Thyristor Electronic Soft Starter For Asynchronous Electric Motor


    NK300 series all-digital AC motor soft starter is a new type of starting equipment which is designed and produced by using power electronics technology, micro-processing technology and current control theory. The product can effectively limit the starting current in the starting process of asynchronous motor, can be widely used in fan, water pump, transportation and compressor and other loads, is a Ideal replacement products of traditional starting equipment such as star/triangle conversion, auto-Coupling and Magnetic-Controlled starter.

    Maintenance


    1.Dust: If too much dust, it will reduce the insulation level of the soft starter, even causes the soft starter does not work.
    Brush the dust with clean and dry brush.
    Remove dust with compressed air machine.
    2. Condensation: If condensation, it will reduce the insulation level of soft starter, even causes the soft starter does not work.
    (1) Blow it with a hair dryer or electric stove.
    (2) Bring it to power distribution room for dehumidification.
    3. Regularly check components' intact. Whether it can work properly.
    4. Check soft starter' cooling channel, ensure they are not clogged by dirt and dust.
    Before maintenance checking, it has to cut off all power in the line side of soft starter.
