Medium Voltage Soft Starters: DriveStart


Ratings: up to 6.6kV, up to 8.5mVA
Introducing the DriveStart, the first of its kind, IGBT based Medium Voltage Soft Starter, optimized for applications that require low starting current and/or a high starting torque. The cutting edge design results in significant savings in costs, energy and space while meeting high demand application requirements.

Experience the Evolution of Soft Starters

New! The Solcon DriveStart is now available up to 8.5mVA. The re-designed DriveStart now includes the innovative Solcon Data Logger and takes up less space then the previous design. Since its launch, the DriveStart has been an international success and has been commissioned across the industrial landscape.

The DriveStart is optimized for applications that require a low starting current and/or a high starting torque:

  • Provides full torque start
  • Starts at nominal motor current or lower
  • Enables motor starting from weak electrical networks
  • Reduces motor heat at start enabling use of standard motors

Saving costs, energy and space while meeting top performance requirements

  • Significantly lower price point than a Medium Voltage VFD, yet providing similar soft start and soft stop features
  • Integrated bypass ensures no energy loss during operation, reducing energy waste and operational costs
  • Peak demand reduction
  • Streamlined design translating to at least 50% reduction in space requirements vs. a VFD with comparable performance

Advanced Features

  • Input voltage – Up to 6.6 kV 50/60Hz +10% -15%.
  • Power range – Up to 6.6kV, 8.5mVA (based on load, higher ratings may be available)
  • Mains starting current – 10% to 120% of motor rated current
  • Starting capacity of 100% of FLC for 600 seconds at 50°C, numerous number of starts
  • Starting torque - Up to 160% of motor rated toque
  • Internal synchronization system (bypass), from DriveStart to mains and back
  • Soft Start and Soft Stop
