Product Profile of Industrial Grade AC Line Choke
Industrial Grade AC Line Choke reduces nuisance over voltage tripping of the drive due to transient voltage spikes and power line notches. The Choke improves input line current balance on the drive input when the line voltage is unbalanced and offer in-rush protection to input rectifiers caused by sudden power line surges or sudden changes in the motor load. The Choke has 50/ 60Hz frequency and range from 0.15 kW to 1200 kW. The Choke has 110/ 230/ 415/ 440/ 480 V AC input voltage. The Choke offer reduction of input line current harmonics by reducing the current form factor thereby improving power factor and reduce ripple current in the DC bus capacitor bank thus extending their life. The Industrial Grade AC Line Choke has single winding/ safe touch terminal/ vacuum pressure impregnation/ earthing terminal construction.
Key Features of Industrial Grade AC Line Choke
- Reduces nuisance over voltage tripping of the drive due to transient voltage spikes and power line notches.
- Improves input line current balance on the drive input when the line voltage is unbalanced and offer in-rush protection to input rectifiers caused by sudden power line surges or sudden changes in the motor load.
- Has 50/ 60hz frequency and range from 0.15 Kw to 1200 Kw
- 110/ 230/ 415/ 440/ 480 V AC input voltage
- Offer reduction of input line current harmonics by reducing the current form factor thereby improving power factor and reduce ripple current in the dc bus capacitor bank thus extending their life.
- Single winding/ safe touch terminal/ vacuum pressure impregnation/ earthing terminal construction.
- Power supply with high frequency transients such as voltage surges, line notching, pulsed distortion and harmonics
- Drive supplied by a low impedance line. If the KVA rating of the ac supply transformer is greater than ten times the input KVA rating of the drive, a 5% input line reactor should be added.
- Power supply with phase unbalance greater than 2% of the voltage. An unbalance greater than 2% can shorten the life of drive and results in severe damage to drive power components.
- Installation having more than two drives installed on the same power line. Multiple drives on a common power line require one reactor per drive to reduce cross talk.
