Harmonic Filters
Reduction of harmonics and low frequency distortion
Improvement of the THD-I values
Compliance with the harmonic emission requirements of IEC 61000-3-12
Less expensive than active harmonic filters
Significantly reduced input current (energy saving)
HFE-A (THD-I <16%*)
HFE-B (THD-I <10%*)
High Performance Harmonicfilter
Current ratings from 10 A up tp 400 A
For power up to 440 kW
380 V – 690 V (50 / 60 Hz), 3-phasig
THD-I up to 5 % is possible (typical 10-16 %*)
Especially for devices with B6 – rectifier bridge
Reduction up to 50th harmonics (2.5 / 3.0 kHz)
Switchable capacitors
No leakage current
For higher requirements
* at R
SCE
 ≥ 66, THD U ≤ 2%
Current without Harmonic filter
Current with Harmonic filter HFE
NF-HPHF
Compakt Harmonic filter
Current ratings 10 A – 75 A
1-phase and 3-phase, 115 V up to 480 V (50 / 60 Hz)
Very compact case design
No leakage current
