Reowavepassive Harmonic Filter Cnw 8981 – 60 Hz

REOWAVEpassive harmonic filter 60Hz / 480 V (IP20)


Reduce harmonic waves on the mains input side of converters – save up to 30% in energy costs. The REOWAVE®passive filters the harmonics caused by the B6 circuit (thyristor, diode bridge, etc.) and motor drives. The supply network is relieved by the compensation of the harmonic reactive power. This enables cost savings in material selection and energy consumption. Starting currents and current peaks are very strongly attenuated. This increases the service life and reliability of electrical systems. Thanks to the compact and ready-to-connect design, easy installation is also possible in existing systems. The REOWAVE®passive helps to comply with the international power quality standards IEEE 519 or EN 61000-3


In addition to the basic equipment, the REOWAVEpassive® can be
ordered as a simple filter with the following additional options:

  • Traffic light function
  • Temperature monitoring
  • potential-free signal contacts
  • Shutdown of the filter function in the event of an error
  • Reduction of the THDI value ≤ 5%
  • Increase in network stability
  • Reduction of the input current up to 30%
  • compact design
  • easy integration into existing systems
  • higher reliability of electrical system
  • optionally with overcurrent indicator to check the filter effect

The options are intended to help you better control the network quality
and send messages to the control centre in the event of errors – so you have full control over your power consumption and at the same time increase operational reliability.
