Description
Three-phase line input AC reactor (ACL-0490-028U-0.4SA) is designed to be installed at the input of frequency converters 220 kW or other electrical drives to eliminate mutual influence of powerful equipment powered from the same network on 3 phases 380 V. The input reactor smoothes current harmonics and makes them more gradual, protecting devices from input overvoltage. The three-phase reactor is constructed as three inductive coils, each of which is connected to a phase via input-output terminals.
Functions of line reactors:
- smoothing current;
- protection against electrical overvoltages;
- improving power efficiency.
