Description:

• The main features are by reducing interference from operating frequency inverters and DC speed regulators to other devices, such as harmonics and waveform distortion.
• Enhance frequency inverter resistance to voltage imbalance.
• (Unbalance degree exceeds 1.8% of rated voltage).
• Protection frequency inverter rectifier modules and associated components are damaged by high capacitive current due to low internal power resistance.
• (When the power supply capacity is five times more than the frequency inverter capacity).
• Improve power factor and reduce harmonic current content in the inverter power supply.
• Reduce current and voltage waveform distortion rates, hence improving power supply quality.
