Medium voltage Soft Starters with new IGBT technology.



The Drive Start from Solcon provides significant technical innovation for starting medium voltage motors with a starting current lower than the rated motor current and torque up to 160 % of nominal torque. This technology allows an almost infinite number of start and substantial energy savings during startup and operation of the motor . Combining benefits and robustness of Thyristors starters with the flexibility and the IGBT Transistor technology, Drive Start presents a soft Starter method significantly lower in price compare to a medium-voltage inverter.
