24: Low temperature, low loss, low cost, utilization rate;

25: The input reactor to limit the form of harmonic wave feedback circuit. They can also be reduced

   because of the converted DC Link Capacitor input rectifier caused by AC current and frequency;

   baseline reactor pressure drop UD = 2%, with a feeder unit for the drive and automatic operation

   of the transformer, but also for uk <1% of the system operation.

Functions:

1. Reduction of harmonic wave,Improvement of the power factor.

2. Over-voltage restriction and clean the power grid.

3. Reducing the stress caused by noise to motorextended the life span of motor.

4. Improvement of low-frequency conduction emission/sensitivity.
