Medium voltage soft starter

Product Description

Advantages 

  • Multiple start curves to adapt different loads

  • Variety sets of parameters in one soft starter to fit wide power range of different motors

  • Use low voltage motor in the field for full functional testing

  • Comprehensive motor protections even in bypass mode.


Features

  • Isolation between high voltage and low voltage circuit.

  • Customized enclosure 

  • Adapt to various load conditions—large inertia load start, frequently changing load start, generator power supply start, synchronous motor start
