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.
