Line filters

Up to 11 kW, MOVITRAC^® B frequency inverters have an integrated line filter as standard. They comply with the following limit value class to EN 61800-3 on the line side without further measures:

• 1-phase connection: C1 cable conducted
• 3-phase connection: C2

No EMC limits are specified for interference emission in voltage supply systems without an earthed star point (IT system). The efficiency of line filters is severely limited.
