Filter combination (single stage)
Description
By using a line reactor the upper harmonics are reduced and the starting current is limited. This increases the efficiency and discharges the leads.
Advantages
- Easy installation
- Small footprint
- Reduction of cable looms in control panels
- Attenuation of higher harmonics
- Low hum vacuum impregnated choke
- Reduced start-up current
- The choke is rated for a short-circuit voltage of 4%, at rated current, as standard
Typical applications
Interference suppression of frequency converters with IGBTs and reduction of harmonics (conforming to VDE 0160/EN 61800-3 class B)
