Soft-Starter – SSW05 Series

WEG soft starters are fitted with micro processors. They are high-tech and were designed to ensure the highest performance during starts and stops of induction motors.

Soft-Starters are electronic starters designed to accelerate, deccelerate and protect three-phase induction motors, controlling the voltage applied on the motor.

The SSW05 Plus Micro Soft-Starters, with DSP control (Digital Signal Processor) have been designed to supply an excellent performance during starting and stopping electric motors with excellent cost/benefit ratio.

The Operator Interface allows easy parameter setting, simplyfying the start-up and operation activities.

The SSW05 Plus Micro Soft-Starters are compact, optimizating the space in electrical panels and incorporates all protections for the driven motor.

Convenience in Motor Start and Protection

SSW05 soft-starters are static starters designed for motor acceleration, deceleration and protection. The control of the voltage applied to the motor, by adjusting the firing angle of the thyristors, provides smooth starts and stops. By properly setting the variables, the obtained torque is adjusted to the load requirement, ensuring the minimum necessary starting current.

The SSW05, featuring DSP control (Digital Signal Processor),  is designed for optimal performance in motor start and stop, with excellent cost effectiveness. They incorporate all the protections for you electric motor, in addition to being easily set, simplifying the start-up activities and daily operations. Their compact dimensions contribute to the optimization of spaces in electrical panels.

 

Applications

The SSW05 soft-starter is especially recommended for applications in:

  • Rotary vane vacuum pump
  • Centrifugal pumps
  • Calenders (starts with no load)
  • Screw compressors (start in relief)
  • Mixers
  • Cellulose refiners
  • Axial fans (low inertia – light load)

Main Characteristics

  • Currents: 3 to 85 A
  • Voltage: 220 to 575 V
  • Control with DSP
  • Remote HMI (optional)
  • Built-in motor protections
  • Built-in RS-485 serial communication

 

Benefits

  • Built-in bypass
  • Control with digital processor (DSP)
  • High efficiency
  • Compact
  • It extends the lifespan of the motor and mechanical devices of the driven machine by eliminating mechanical shocks
  • Easy to operate, adjust and service
  • Simple electrical installation
  • Operation in environments up to 55 °C
  • Great reduction of the stresses on the couplings and driving devices (gear boxes, pulleys, gears, belts, etc.) during the start
