Save and perfectly matched products for drive enginnering

By using modern frequency converters, the drive technology becomes more and more energy efficient. Due to the frequency converters, these powerful controllers produce strong electrical noise on the motor cable that adversely affect the engine and other consumers.

To ensure reliable and durable operation of all drive components, the electrical noise must be reduced as far as possible. Basically, many different factors such as volage rise (dv / dt), fault and surge currents, EMC behavior, harmonics, etc. must be observed.

Targeted measurements and perfectly matched products

Since these physical effects often occur in combination, targeted and well-coordinated measurements additional components are important. For the most diverse applications REO always offers the best electronic, inductive and resistive components.

Line chokes, EMC filter, DC reactors, chokes or sinusoidal and dv / dt filters are just a few examples of products, by which REO guarantees a safe and trouble-free operation in drive technology.

Water-cooled components for high performance or fully encapsulated systems with high protection classes are examples of our innovative strength. Many years of experience and the highest quality standards make REO a strong partner.

Customized solutions

  • Series WKO

    Closed loop current transformers

    Series WKO
    • Primary rated current: 25 - 2000 A
    • Frequency range: 100000 - 200000 Hz

    WKO current sensors work in accordance with the proven compensation principle and are suitable for measuring direct, alternating and mixed currents.

    The primary current generates a magnetic flux, which is compensated by an internal secondary coil. The current is evaluated by an electronic circuit and a Hall sensor. The secondary compensating current is a precise representation of the primary current to be measured. 

    According to: 

    • EN50178
    • EN50121, EN55011
    • IEC61869-1, IEC61869-8, IEC61010-1 
    • UL94-V0 – UL Norm: all parts are UL-listed

    Applications

    • Power Electronics: AC DC motor control, inverter technology, drive control
    • Railway Technology: drive control
    • Renewable energy: wind turbines control, monitoring

     

    General technical data:

    • Accuracy: better than 1%
    • Ambient temperature:    -25°C … +70°C
    • Storage temperature: -25°C … +85°C
