VTdrive What is VSD Input Choke0 pages

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
