Productos seguros y perfectamente armonizados entre sí para la tecnología de accionamiento

La técnica de accionamiento es cada vez más eficiente desde el punto de vista energético gracias a modernos convertidores de frecuencia. Condicionados por su diseño, estos controladores de alto rendimiento generan fuertes interferencias eléctricas en las líneas de alimentación del motor, que son perjudiciales para el motor y para otros consumidores.

A fin de garantizar un funcionamiento fiable y duradero de todos los componentes de accionamiento es necesario reducir, tanto como sea posible, las interferencias eléctricas. En este contexto existen muchos factores a considerar, como la velocidad de aumento de tensión (du/dt), la corriente parásita y de sobrecarga momentánea, el comportamiento electromagnético, armónicos, etc.

Mediciones in situ y productos perfectamente armonizados entre sí

Dado que estos efectos físicos se presentan a menudo en combinación, las mediciones específicas y los componentes adicionales perfectamente armonizados entre sí juegan un papel determinante. REO ofrece siempre los mejores componentes electrónicos, inductivos y resistivos para diferentes aplicaciones.

Reactancias de red, filtros EMC, reactancias de circuito intermedio, reactancias de motor, filtros sinusoidales y du/dt son sólo algunos ejemplos de los productos con lo que REO garantiza un funcionamiento seguro y sin problemas en la técnica de accionamiento.

Componentes refrigerados por agua para altos rendimientos o sistemas totalmente encapsulados con altas clases de protección son sinónimo de nuestra fuerza innovadora. Muchos años de experiencia y los más altos estándares de calidad hacen de REO un socio dotado de solidez.

  • CNW 897

    Three-phase harmonic filter (400 V/50 HZ)

    CNW 897
    • Tensión nominal: 400 V
    • Corriente nominal: 25 - 600 A
    • Inductance of the choke: 0,2 - 2,9 mH

    The filter is designed for the reduction of the THD (Total Har-monic Distortion) when used with B12 rectifiers. The harmonic currents are extremely suppressed so that the THD is reduced to lower than 5 % (for example in UPS-systems)


    Typical values of Total Harmonic Distortion with B12 rectifiers and use of transformers are between 12 and 13%. This complies with the EN 61000-3-4 and EN 61000-3-12 standards.


    If more severe conditions for the mains are defined, in addition to the transformer it is necessary to use REO-Harmonic-Filter type CNW 897. These filters are available in two different versions:



    • THD < 5%

    • THD < 10 %


    The IP00 version is especially suitable for panel mounting and can be mounted to save space here. The CNW 897 helps to comply with international power quality standards IEEE 519 or EN 61000-3 .

    Power Noise Reduction - save energy costs. 


    The DC-link choke is used for smoothing the DC link current and to reduce mains harmonics in voltage source inverters.


    The typical combinations of rectifiers and capacitors strains the supply network significantly. For functional reasons, the current consumption of the power supply or the inverter is not sinusoidal but pulsed at the moment of maximum voltage. DC-link chokes reduce the harmonics and relieve the supply network similar to the mains choke. In addition, the DC-link choke attenuates charging current peakssurges of the DC-link capacitors. By using a DC-link choke the supply network is less burdened with harmonic reactive power.


    Improvement of the efficiency of a converter (Power Factor Correction). Starting currents and current peak are attenuated up to 70%. Mains chokes help to comply with international power quality standards IEEE 519 or EN 61000-3-2.

    Sinusoidal output current - save costs and trouble-free operation.


    For particularly long cable lengths of > 100m between inverter and motor the shielded cable for EMI suppression used can cause a capacitive coupling. A conventional motor choke can not provide sufficient damping in such cases.


    The sinusoidal filter is a low pass from inductance and capacitance and has a very low resonance frequency. So it is able to generate a largely sinusoidal current. The operation and the loss balance of the asynchronous motor behave like the normal mains operation. The typical motor noise with converter do not occur and a shielded cable to the motor can be dispensed. Losses and heating are greatly minimized and the leakage current will be reduced. Longer motor cable lengths are possible. The motor insulation is protected, thus increasing the service life.


    The sinusoidal filter also attenuates the conducted interference in lower frequency range very good. The losses and the typical noise in the motor plate can be reduced.
