Filter combinations, single-stage
Description
By using a mains choke, harmonics are reduced and the inrush current is limited. This improves efficiency and reduces the load on the line.
Benefits
- faster and more convenient installation
- small footprint
- Reduction of cable strands in the control cabinet
- Damping of current harmonics
- Choke with low noise due to vacuum impregnation
- Inrush current limitation
- Mains choke standard for short-circuit voltage of 4% at rated current
Typical applications
Suppression of frequency converters with IGBTs with simultaneous reduction of harmonics (according to VDE 0160/EN 61800-3 Class B)
