I. Overview
Input and output reactors for variable frequency drive (VFD) systems are designed to protect VFDs and speed controllers. During operation, these devices often face surge currents and surge voltages, which can significantly damage performance and shorten lifespan. Installing an input reactor at the input side suppresses surge voltage and current, protects the VFD or speed controller, extends its service life, and mitigates harmonic interference.
Since VFDs regulate speed through variable frequency, high-order harmonics and waveform distortions may occur during operation, affecting normal performance. An output reactor at the output side filters harmonic voltage and current, improving power quality. Our input/output reactor series are manufactured using high-quality silicon steel sheets with specialized processes, offering compact size, low temperature rise, and noiseless operation.
These reactors are compatible with a wide range of VFD brands including Siemens, SanKen, Hitachi, Toshiba, Panasonic, Yaskawa, Inovance, Danfoss, Fuji, Eurotherm, LG, OMRON, Hyundai, Schneider, Lenze, Emerson, Conver, and more.
II. Model Explanation
III. Product Features -
Power supply may cause noticeable interference to other equipment (disturbances, overvoltage). - Phase-to-phase voltage imbalance 1.8% of rated voltage. - Low-impedance lines (power transformers over 10 times the VFD rated value). - Multiple VFDs installed on a single line to reduce line current. - Use of power factor correction capacitors or power factor correction units (cosφ).
IV. Operating Conditions -
Altitude: ≤ 1000 meters. - Ambient temperature: -25°C to +45°C; relative humidity ≤ 90%. - Ensure proper ventilation; if installed inside cabinets, additional ventilation equipment is required.
