WEG SSW900 series soft starters are designed for heavy-duty, high-performance motor starting and stopping applications. The SSW900 soft-starters feature a microprocessor, are totally digital, incorporate state-of-the-art technology and are designed to ensure the best performance in the start and stop of induction motors, being a complete, low-cost solution.
Features
- Current ranges from 10 to 1,400 A
- Supply voltage from 220 to 575 V ac (T5) or from 380 to 690 V ac (T6)
- Oriented start-up
- Standard connection (3 cables) or motor inside delta connection (6 cables)
- Integral motor thermal protection
- Reduction of voltage drops during motor start
- Pump control function for smart control of pumping systems that prevent water hammer and pressure overshoots in the hydraulic piping
- Great mechanical stresses reduction on the couplings and transmission devices (gear boxes, pulleys, gears, belts, etc.) during the motor start
- Increased motor and equipment lifetime
- Elimination of starting mechanical shock to couplings and driven equipment
- Operation at ambient temperature up to 55 °C without current1) derating
- Three braking methods to stop the motor and the load faster. Braking methods with or without external contactors
- Built-in bypass: minimizing power losses and heat dissipation in the thyristor, providing space reduction, contributing to energy saving and increasing the product’s life
Advantages
The SSW900 can substitute direct online starters or star-delta starters, bringing benefits to your application, such as:
- Electric energy savings
- Greater protection and increased durability of the electric motor
