DC reactor 3 hp for vfd, improve the input current wave caused by capacitor harmonics, small size and light weight.
Features1. Improve the input current wave caused by capacitor harmonics.2. Reduce and prevent rectifier bridge damage and capacitors.3. Overheating due to a surge in current.4. Improve the power factor and reduce the AC pulse of the DC bus.5. Limit transient changes in system voltage.
Dimension (unit: mm)Tips:
In the lifting industry, since AC reactors cannot be omitted, the harmonic reduction effect of AC reactors is basically the same as that of DC reactors. At the same time, using AC and DC reactors can reduce harmonic interference better, but it also increases the voltage loss on the motor side (there are 1% to 3% voltage drops on AC and DC reactors). Therefore, ATO recommends replacing AC reactors with AC reactors.
