SSW05

WEG ​SSW05 soft-starters are designed for motor acceleration, deceleration and protection. The power range is from 1.1-45kW. 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.

Applications:

• 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)

Benefits:

• Built-in bypass
• Control with digital processor (DSP)
• High efficiency
• Compact
• Lifespan of the motor extended 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
