The filters are checked by us manually and only released for you after careful quality control.

REO is a leading manufacturer of inductive components and systems.

Since its foundation in 1925, REO has been helping customers regulate current and voltages. The development and manufacture of high quality inductors, helping our customers to ensure Power Quality (PQ) has played a central role in our business.

Today‘s wide range of EMC components, such as inductors, transformers and RF and Harmonic filters demonstrate our comprehensive knowledge and expertise.

This coupled with fresh ideas and innovation, enable us to provide our customers with products that provide superior functionality and reliability. We offer standard products, as well as client specific solutions in drive technology, railway engineering, renewable energy and electric transportation.

The propagation of interference

The use of electrical and electrical equipment is becoming more widespread. However to ensure safe and reliable operation, electromagnetically compatible conditions must exist i.e. a device must be able to work satisfactorily in its electromagnetic environment and without itself causing unacceptable electromagnetic inference in the same environment.

Electromagnetic inference can cause various faults that are often difficult to diagnose. Crackling and hissing on a radio receiver, data errors and processor glitches in computer engineering and even the breakdown of isolation are all possible effects. To ensure compliance with relevant EMC directives and to avoid instances of interference, appropriate EMC filters must be used.

Electromagnetic interference can be propagated in various ways. The nature of that propagation depends on the frequency involved. EMC filters are used to suppress conducted inference by maximizing the impedance mismatch between line and load. The filtering effect works in both directions. This means that interference from the power-consuming device to the network as well as from the network to the power-consuming device is damped.

Limits on radio interference voltage

A number of EN (European norms) specify limits on radio interference voltages. These EN regulations differentiate between use in residential or light
industrial areas (Class A) and in industry (Class B). To make it easier to select the correct filter and where possible, the classification is shown in our catalogue.
