Product Description
AC Line Choke Load Reactor for Variable Frequency Drives
High-performance AC choke output reactor designed for 5.5kW, 7.5kW, 11kW, and 15kW AC drives, featuring F/H class insulation for superior thermal performance and reliability.
Primary Function
This filter reactor is engineered for low-voltage filter cabinets, connected in series with filter capacitors to create tuned resonance circuits that effectively absorb harmonic currents from power grids. It addresses harmonic pollution generated by rectifiers, converters, and frequency converters, protecting main transformers and electrical equipment while improving system power factor.
Key Performance Benefits
- Reduces harmonic interference and waveform distortion from frequency converters and DC speed regulators
- Enhances frequency converter resistance to voltage unbalance exceeding 1.8% of rated voltage
- Protects rectifier modules and components from peak capacitive currents when power supply capacity exceeds inverter capacity by 5 times
- Improves power supply power factor and reduces harmonic current content
- Minimizes current and voltage waveform distortion rates for improved power quality
