Active filter technology is the result of extensive research, and it has been proven to provide lowered disturbances, lower current consumption and increased production stability, just to name a few.
The active filter power range fluctuates between 30 A up to 2,800 A with 400 VAC to 690 VAC on the active side. They can either be wall-mounted up to 120 A or in complete cabinet IP21/40 construction. Load current transducers are mounted separately.
Possible active filter connections to the grid:
|Input voltage||200 V…480 V +/-10%||3-wire|
|200 V…400 V +/-10%||4-wire|
|480 V…690 V +/- 5%||Over 400 A phase current compensation only||3-wire|
|Filter current||60 A…300 A||Phase||3-wire|
|180 A…900 A||Neutral||4-wire|
|300 A…3000 A||Phase||3-wire|
|Grid frequency||50/60 Hz +/-3 Hz|
|Compensation||Up to 50th harmonic||Simultaneous selectable|
|Power factor correction||-100% > PF < 100%||Inductive or capacitive|
|Filter functions||Reactive power and/or harmonics compensation||High reliability|
|Multiple harmonic compensation simultaneously|
