KEB COMBILINE Harmonic Filter
Achieving sinusoidal harmonic current from standard 6 pulse rectifier load has always been a challenge. Historically this could only be accomplished through the use of costly components and more complicated rectification schemes.
The KEB COMBILINE harmonic filter is an innovative solution for equipping machines or retrofitting production systems. The compact design of the filter (patent pending) is available in two types:
- standard series with THD (total harmonic distortion) smaller than or equal to 8%, PWHD smaller or equal to 15% in power settings 4 - 460 A.
- economy series with THD smaller than or equal to 15%, PWHD smaller or equal to 38%. According to standard EN 12015 (european elevator/escalator norm) in power settings 2 - 63 A.
Larger power settings can be covered with connecting filters in parallel.
