External input choke
Contents of this chapter
This chapter describes about external input chokes available for the R0...R2 (2.6A
to 25A) frame sizes. In R0...R5 (33 A to 293 A) frame sizes, built-in DC swinging
choke is provided by default. DC swinging choke reduces 20% more harmonics in
partial loads due to its patented swinging choke technology and also helps in
protecting the drive from input variations and reduces DC ripple content.
Why external input chokes are required?
The external input choke protects against voltage spikes and reduces harmonics
in the line supply.
