Product Profile of Single/ Three Phase Ac Line Choke

Single/ Three Phase AC Line Choke is used between variable speed drives and utility and can be used to dampen the harmonic content and rush of the current drawn by the motor drive. The Choke is used to protect the drive from harmful line disturbances and help prevent equipment failure and down time. The Choke reduces nuisance over voltage tripping of the drive due to transient voltage spikes and power line notches and improves input line current balance on the drive input when the line voltage is unbalanced. The Single/ Three Phase AC Line Choke offer in-rush protection to input rectifiers caused by sudden power line surges or sudden changes in the motor load and offer reduction of input line current harmonics by reducing the current form factor thereby improving power factor.
