"WEG" Medium Voltage Soft-Starter - SSW7000 Series
 Developed to ensure excellent performance, it prevents mechanical shocks from the load, protects the motor against related burnouts or current surges in the power supply and thus, offers prepackaged and engineered solutions for various applications including Marine & Mining.


   

Main Features

  • Integrated bypass
  • Circuit breakers are not required because there is a line contactor
  • Motor protection built-in in the standard cabinet
  • Heavy duty design at 50 °C ambient temperature (above 40 °C with current derating)
  • User friendly configuration and operation
  • Fibre-optic firing
  • Complete isolation between MV and LV compartments

 

Features

  • Motor Voltage: 2.3 kV to 6.9 kV
  • Torque control - FTC - Flexible Torque Control, technology developed by WEG which uses the vector control and control of direct torque concepts, based on technologies developed for the vector frequency inverters CFW. The FTC is flexible to select the desired torque control according to the type of load applied to the motor (constant loads, quadratic loads, or loads with lower or higher starting torque), providing a smooth start with a linear speed ramp along the entire starting process
  • Accessories can be easily and quickly installed by using the Plug & Play concept
  • Protection degree: IP41 or NEMA 12
  • Operating interface (HMI) with graphic LCD
  • Real-time clock
  • Medium voltage fuses
  • Power and control insulated by fiber optics
  • Main and Bypass Vaccum Contactors able to perform DOL start
  • Flash memory module (accessory)
  • SoftPLC function
