EN600 series high performance flux vector control frequency inverter
Why use frequency inverter
1.Frequency inverter is widely used in industrial field to adjust motor speed and reduce the starting current.
2.After using the frequency inverter, the reactive power is reduced, and the active power is increased because of the effect of the filter capacitor in frequency inverter.
3.Using the frequency inverter soft start function,starting current will start from zero and not exceed the maximum rated current,reducing the impact on power loss and the power supply capacity to prolong the service life of equipment and valves.Meanwhile save equipment maintenance cost.
