VTdrive What is Variable Speed Drive VSD Input Choke

Product catalog summary
Introduction to Input Chokes:
Input chokes are essential components used to reduce power supply harmonic currents and the overall input current to drives. They also offer additional protection against voltage spikes from the mains.

Functionality and Benefits:
  • Input chokes help in minimizing supply line harmonic currents and voltage distortion, which are common issues with inverter drives.
  • They provide enhanced protection against transient voltages and other mains-borne interferences.

Application Recommendations:
  • Input chokes are recommended for all installations, especially where the local mains supply quality is poor or unknown.
  • They are crucial in environments with high current switching loads, such as large DC drives or soft starts.
  • They are beneficial in areas with low mains supply impedance and remote locations prone to lightning strikes.

Product Availability:
Input chokes are available for the complete range of VTdrive VFD products, ensuring compatibility and optimal performance.

VTdrive What is Variable Speed Drive VSD Input Choke-1

Input Chokes Reduce power supply harmonic currents Reduce the overall input current to the drive Provide additional protection against mains borne voltage spikes Input chokes can be used to reduce the supply line harmonic currents and voltage distortion generated by almost all inverter drives on the market today. VTdrive VFD have selected a range of chokes matched to the VTdrive VFD range to provide the best reduction in supply current harmonics whilst also providing enhanced protection for the VTdrive VFD against transient voltages ('spikes') or other mains borne interference. Input chokes are available for the complete range of VTdrive VFD products, and are recommended for use in all installations and in particular: where the local mains supply quality may be poor or unknown where high current switching loads such as large DC drives or soft starts are operating where the mains supply impedance is low in remote areas prone to lightening strikes Shenzhen VTdrive Technology Co.,Ltd.
