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
