Professinal china vfd manufacturers

SKI-V series is Four quadrant china vfd manufacturers with vector control technique and energy regeneration technique, having the excellent motor control performance. Adopting the double PWM control technique to increase the power factor of system and realize the Four quadrant running of the motor and meet the speed adjust requirements of various loading can transform the regenerative power of the motor to electric energy getting back to the electricity grid in order to achieve the purpose of saving maximum energy. Moreover, it can reduce the harmonic pollution, the power factor is near to 1, it's a real green frequency inverter.
